How to Measure for Wallpaper: A Comprehensive Guide

Are you looking to transform your home with the timeless elegance of wallpaper? Maybe you envision a striking accent wall, a room bathed in captivating patterns, or even an entire house exuding your unique style. But before you dive into the world of wallpaper, the crucial first step is accurate measurement. Measuring for wallpaper might seem like a simple task, but getting it right ensures you order the correct amount, minimize waste, and achieve a flawless finish. This comprehensive guide will walk you through the process, step by step, making sure your wallpapering project gets off to the perfect start. So, grab your measuring tape, and let's get started, guys!

Why Accurate Measurement Matters

Before we delve into the how-to of measuring, let's discuss why accurate measurements are so vital for a successful wallpapering project. Think of it like this: wallpaper isn't exactly cheap, and you don't want to end up with too little (causing delays and requiring additional orders) or too much (wasting your hard-earned cash). Here's a breakdown of why precision is key:

Cost Savings: Accurate measurements prevent overspending on wallpaper. By knowing the exact amount you need, you avoid buying extra rolls that will likely end up unused. This is especially crucial for patterned wallpapers, where matching the design across seams often requires purchasing more than you might initially think. With precise measurements, you can confidently calculate the number of rolls needed, keeping your budget in check.
Waste Reduction: Overbuying wallpaper not only impacts your wallet but also contributes to unnecessary waste. Excess wallpaper often ends up in landfills, which isn't ideal for the environment. Accurate measurements help you minimize waste by ensuring you only buy what you need. By planning ahead and measuring carefully, you can reduce your environmental footprint while still achieving your desired aesthetic.
Seamless Application: Imagine spending hours hanging wallpaper only to discover you're short a roll or two. This can lead to frustration, delays, and a less-than-perfect final result. Accurate measurements guarantee you have enough wallpaper to complete the job seamlessly. You'll be able to match patterns, avoid unsightly gaps, and achieve a professional-looking finish that you'll be proud to show off. So, take your time, measure carefully, and set yourself up for success!
Pattern Matching: If you've chosen a wallpaper with a pattern, accurate measurements are even more critical. You need to ensure that you have enough wallpaper to match the pattern repeats correctly across each strip. This often means buying extra wallpaper to account for the waste that occurs when aligning the design. Precise measurements, combined with an understanding of the pattern repeat, will help you determine the total amount of wallpaper needed for a cohesive and visually appealing result. This is where the expertise comes in, and we're here to guide you every step of the way.

In short, taking the time to measure accurately is an investment in the success of your wallpapering project. It saves you money, reduces waste, ensures a seamless application, and allows for perfect pattern matching. So, let's get to the nitty-gritty and learn how to measure like a pro!

Tools You'll Need

Before you start measuring, gather your essential tools. Having everything at hand will make the process smoother and more efficient. Here's a checklist of what you'll need:

Measuring Tape: A sturdy and reliable measuring tape is your most important tool. Opt for one that's at least 25 feet long to handle most wall sizes. Make sure the tape is in good condition and doesn't have any kinks or bends that could affect accuracy. A metal measuring tape is generally more durable and easier to use than a cloth one.
Pencil: You'll need a pencil to mark measurements on the walls and take notes. A standard #2 pencil works perfectly fine. Avoid using pens or markers, as they can bleed through the wallpaper or leave permanent marks on your walls.
Paper and Notepad: Keep a notepad or a piece of paper handy to jot down your measurements as you go. It's easy to forget numbers, so writing them down ensures you have an accurate record of your calculations. Organize your notes clearly, labeling each measurement to avoid confusion later.
Calculator: A calculator will be helpful for adding up measurements and calculating the total square footage of your walls. You can use a physical calculator or the calculator app on your smartphone. Accuracy is key, so double-check your calculations to avoid errors.
Step Ladder (Optional): If you have high ceilings, a step ladder will be necessary to reach the upper portions of the walls. Choose a ladder that's sturdy and provides a safe and stable platform to work from. Always follow the manufacturer's instructions for safe ladder use.
Laser Measure (Optional): For larger rooms or complex spaces, a laser measure can be a time-saving and accurate alternative to a traditional measuring tape. Laser measures use a laser beam to determine distances, making it easier to measure long stretches of wall or across a room. However, they can be more expensive than measuring tapes, so consider whether the investment is worthwhile for your project.

With your tools gathered, you're now ready to move on to the actual measuring process. Remember, accuracy is the name of the game, so take your time and double-check your work. Let's get those walls measured, guys!

Step-by-Step Guide to Measuring Your Walls

Okay, guys, now for the main event! Let's get down to the nitty-gritty of measuring your walls for wallpaper. Follow these steps carefully, and you'll be well on your way to a perfectly wallpapered space:

1. Measure the Width of Each Wall

Start by measuring the width of each wall you plan to wallpaper. Hold your measuring tape horizontally along the base of the wall, from one corner to the next. Make sure the tape is straight and taut for an accurate measurement. Write down each wall's width in your notepad, labeling it clearly (e.g., "Wall 1: 12 feet").

Repeat this process for every wall in the room, including any sections above doors or windows. It's crucial to measure each wall individually, as widths can vary slightly even in seemingly symmetrical rooms. Don't assume that opposite walls are the same width; always double-check.

For walls with architectural features like alcoves or built-in cabinets, measure the width of each section separately. This will ensure you account for every surface that needs wallpapering. You might even sketch a rough diagram of the wall layout in your notepad to help you keep track of the measurements.

2. Measure the Height of Each Wall

Next, measure the height of each wall from the baseboard to the ceiling. Hold your measuring tape vertically, starting at the floor and extending to the ceiling. Again, ensure the tape is straight and taut for an accurate reading. Record the height of each wall in your notepad, labeling it clearly (e.g., "Wall 1 Height: 8 feet").

If your room has variations in ceiling height, such as a sloped ceiling or a dropped soffit, measure the height at the tallest and shortest points. You'll need to use the tallest height to calculate the amount of wallpaper needed, as this ensures you have enough material to cover the entire wall. Similarly, if you have a chair rail or other wainscoting, measure the height from the baseboard to the top of the chair rail, and then separately measure the height from the chair rail to the ceiling.

3. Account for Doors and Windows

Now, you need to account for doors and windows. Measure the width and height of each door and window opening. Write these measurements down in your notepad, labeling them clearly (e.g., "Window 1: 3 feet wide x 4 feet high").

While you won't be wallpapering the actual door or window, you'll need to subtract their area from the total wall area to avoid overestimating the amount of wallpaper needed. However, keep in mind that you'll likely need to order some extra wallpaper to account for pattern matching around doors and windows, so don't subtract too much.

4. Calculate the Total Wall Area

For each wall, multiply the width by the height to calculate the area in square feet. For example, if a wall is 12 feet wide and 8 feet high, the area is 12 feet x 8 feet = 96 square feet. Write down the area for each wall in your notepad.

Next, add up the areas of all the walls you plan to wallpaper. This will give you the total wall area in square feet. This number is crucial for determining how much wallpaper you'll need to purchase. Double-check your calculations to ensure accuracy.

5. Calculate the Area of Doors and Windows

For each door and window, multiply the width by the height to calculate the area in square feet. For example, if a window is 3 feet wide and 4 feet high, the area is 3 feet x 4 feet = 12 square feet. Write down the area for each door and window in your notepad.

Add up the areas of all the doors and windows. This will give you the total area of openings that won't be wallpapered. As mentioned earlier, you'll subtract this area from the total wall area, but keep in mind the need for extra wallpaper for pattern matching.

6. Subtract Door and Window Area (Optional)

Now, you can subtract the total area of doors and windows from the total wall area. This will give you a more precise estimate of the wallpaper needed. However, it's often recommended to skip this step and order a bit more wallpaper than you think you need, especially for patterned wallpapers.

7. Determine Wallpaper Roll Coverage

Check the wallpaper label or product information to find out the square footage covered by a single roll. This information is usually provided by the manufacturer and is essential for calculating how many rolls you'll need.

Keep in mind that the usable square footage of a wallpaper roll is often less than the total square footage due to pattern matching and trimming. For patterned wallpapers, you'll need to factor in the pattern repeat, which is the vertical distance between identical points in the pattern. A larger pattern repeat means more waste and more rolls needed.

8. Calculate the Number of Rolls Needed

Divide the total wall area (or the wall area minus doors and windows, if you subtracted) by the square footage covered by a single roll. This will give you the number of rolls needed. Round up to the nearest whole number, as you can't buy fractions of rolls.

For patterned wallpapers, it's a good idea to add an extra roll or two to account for pattern matching and potential errors. It's always better to have too much wallpaper than not enough, as dye lots can vary between batches, making it difficult to match colors if you need to order more later.

9. Consider Pattern Repeat (Crucial for Patterned Wallpaper)

If you've chosen a patterned wallpaper, understanding the pattern repeat is crucial for accurate roll calculation. The pattern repeat is the vertical distance between identical points in the pattern. This measurement determines how much wallpaper will be wasted when matching the pattern across seams.

To account for pattern repeat, you'll need to calculate the number of full pattern repeats that fit within the height of your walls. Then, add an extra repeat to each strip to ensure proper matching. This extra length will be trimmed off, but it's necessary to achieve a seamless look.

Consult the wallpaper manufacturer's instructions for guidance on calculating the extra wallpaper needed for pattern matching. Some manufacturers provide calculators or charts to help you with this process. If you're unsure, it's always best to err on the side of caution and order an extra roll or two.

10. Double-Check Your Measurements and Calculations

Before placing your wallpaper order, take the time to double-check all your measurements and calculations. Accuracy is paramount, and a small mistake can lead to significant problems down the line. Review your notes, recalculate the wall areas, and ensure you've factored in pattern repeat if necessary.

It's also a good idea to have someone else review your measurements and calculations. A fresh pair of eyes can often spot errors that you might have missed. If you're unsure about any aspect of the measuring process, don't hesitate to seek advice from a professional wallpaper installer or a knowledgeable salesperson at a wallpaper store.

By following these steps carefully, you can confidently measure your walls and order the correct amount of wallpaper for your project. Remember, guys, preparation is key to a successful wallpapering job. So, take your time, be precise, and enjoy the process of transforming your space!

Tips for Tricky Spaces

Okay, so we've covered the basics of measuring for wallpaper, but what about those tricky spaces that don't quite fit the standard mold? Don't worry, guys, we've got you covered! Here are some tips for measuring walls with obstacles, angles, or other unique features:

Sloped Ceilings: Sloped ceilings can be a bit of a challenge, but with a methodical approach, you can measure them accurately. First, measure the height of the wall at its tallest point and at its shortest point. Use the tallest height for your calculations to ensure you have enough wallpaper. Then, measure the width of the wall along the floor. When hanging the wallpaper, you'll need to trim the excess at the angle of the slope, so be sure to have a sharp cutting tool handy.
Arched Doorways or Windows: Arches add a touch of elegance to a room, but they also require some extra attention when measuring for wallpaper. Measure the width of the opening at its widest point. For the height, measure from the floor to the highest point of the arch. When calculating the wallpaper needed, treat the arched area as a rectangle with the same width and height, then add a bit extra for trimming and pattern matching around the curve.
Staircases: Wallpapering a staircase can be a dramatic way to enhance your home's interior, but it also presents some unique measuring challenges. Staircases typically have angled walls and varying ceiling heights, so precise measurements are essential. Measure the width and height of each section of the wall along the staircase, treating each section as a separate rectangle. Pay close attention to the angles and slopes, and be prepared to do some extra cutting and trimming when hanging the wallpaper. It might be helpful to create a detailed diagram of the staircase walls and label each measurement clearly.
Corners: Measuring corners might seem straightforward, but it's important to be accurate, especially in older homes where walls might not be perfectly square. Measure the width of the wall leading up to the corner, and then measure the width of the adjacent wall. If the corner is not perfectly 90 degrees, you might need to adjust the wallpaper slightly when hanging it to ensure a smooth transition.
Built-in Shelves or Cabinets: When measuring a wall with built-in shelves or cabinets, measure the wall as if the shelves or cabinets weren't there. Then, measure the width and height of each individual section of the wall that will be wallpapered around the built-ins. Add these measurements together to get the total wall area. Remember to account for any pattern matching that might be required around the shelves or cabinets.
Uneven Walls: If your walls are uneven or have textured surfaces, it's important to account for these irregularities when measuring. Use a flexible measuring tape that can conform to the contours of the wall. For deeply textured walls, you might want to add a bit extra to your measurements to ensure you have enough wallpaper to cover the surface completely.

By tackling these tricky spaces with a bit of extra care and attention, you can achieve a professional-looking wallpapering job in any room. Remember, guys, the key is to break down the complex areas into simpler shapes and measure each section individually. And if you're ever feeling overwhelmed, don't hesitate to seek help from a professional.

Ordering Your Wallpaper

Alright, guys, you've measured your walls like a pro, conquered those tricky spaces, and crunched the numbers. Now comes the exciting part: ordering your wallpaper! But before you click that "Buy" button, let's go over a few key considerations to ensure a smooth and successful purchase:

Check Dye Lots: This is super important, guys! Wallpaper is printed in batches, and each batch can have slight variations in color and tone. These variations are known as dye lots. To ensure a consistent look across your walls, it's crucial to order all your wallpaper from the same dye lot. When you're placing your order, double-check that all the rolls you're buying have the same dye lot number. If you're ordering online, look for a dye lot or batch number on the product page. If you're buying in person, check the labels on the rolls. If you're unsure, ask a salesperson for assistance.
Order Extra: We've said it before, and we'll say it again: it's always better to have too much wallpaper than not enough! Ordering an extra roll or two can save you a lot of headaches down the line. Extra wallpaper is useful for pattern matching, dealing with mistakes, and making future repairs. Plus, if you decide to wallpaper another area of your home, you'll already have some on hand. A good rule of thumb is to add at least one extra roll for every 10 rolls you're ordering, or even more if you have a large pattern repeat or complex room layout.
Consider Return Policies: Before placing your order, review the seller's return policies. Some retailers have strict rules about returns, especially for wallpaper. Make sure you understand the terms and conditions, including any restocking fees or deadlines. It's also a good idea to inspect your wallpaper as soon as it arrives to ensure there are no defects or damages. If you encounter any issues, contact the seller immediately to arrange for a return or exchange.
Calculate for Waste: We've talked about the importance of pattern matching, but it's worth reiterating that patterned wallpapers generate more waste than plain ones. When calculating the number of rolls needed, factor in the pattern repeat and add extra wallpaper accordingly. A general guideline is to add 15-20% extra for small pattern repeats and 25-30% extra for large pattern repeats. This will help you avoid running short and having to order more, which could result in dye lot mismatches.
Read Reviews: Before committing to a particular wallpaper or seller, take a moment to read reviews from other customers. Reviews can provide valuable insights into the quality of the wallpaper, the accuracy of the product descriptions, and the seller's customer service. Pay attention to comments about color accuracy, ease of installation, and durability. Reviews can help you make an informed decision and avoid potential disappointments.
Don't Forget Primer and Paste: In addition to wallpaper, you'll also need primer and paste to complete your project. Primer prepares the walls for wallpapering, creating a smooth and even surface for adhesion. It also helps to prevent the wallpaper from absorbing moisture from the wall, which can cause bubbling or peeling. Wallpaper paste is the adhesive that bonds the wallpaper to the wall. Choose a paste that's specifically designed for your type of wallpaper (e.g., non-woven, vinyl, or traditional). Make sure to calculate the amount of primer and paste you'll need based on the total wall area.

By following these tips, you can confidently order your wallpaper and look forward to transforming your space. Remember, guys, a little bit of planning and preparation goes a long way in ensuring a successful wallpapering project. So, take your time, do your research, and get ready to create the walls of your dreams!
