Estimating has gotten more difficult with the wide array of wallcoverings available today. This is true since there was originally just one standard roll size, typically 10.05 meters long and 52 centimeters broad. However, wide-width wallpapers nowadays are readily accessible, and the pattern repetitions have grown. These wallpapers range in width from 62 cm to 1 meter. Additionally, wallpaper is offered in panels, often the repetition size. And to aid you greatly, we have made this post on Wallpaper Quantity and Price Calculator.

How to Calculate Wallpaper Quantity and Price

You can Calculate Wallpaper Quantity and Price in the following ways:

Step 1: Measure the length of each wall that will be wallpapered.

Place one end of a tape measure in one of your wall’s borders, then stretch it outward to the other side. To ensure you have a little more when you need to compute, record the measurement executed to the next whole number after you get to the other end. Continue measuring the lengths of all the walls you want to wallpaper and make a note of each one so you remember.

Step 2: Find the height of the walls you want to wallpaper.

To ensure you don’t overestimate what you need, locate the highest point on your wall and take measurements there. Your tape measure should have one end against the wall and the other extended upwards toward the ceiling. You may discover the measurement by pulling the tape measure out when it hits the floor. For some more wallpaper, round your value to the next whole number.

Step 3: Convert your dimensions to feet or meters.

You must adjust whatever measurements you obtain since the wallpaper is often measured in square feet or meters. To get the total length in feet, if you measured the lengths and widths in inches, reduce each measurement by 12. Divide the values by 100 to get the wall’s size in meters if you obtained the length in cm.

Step 4: To calculate the surface area, multiply the entire length of the walls by their height.

Add the lengths of the walls you measured to get the perimeter you are covering with wallpaper. To get the overall surface area of the room, multiply the whole perimeter by the wall height. If necessary, use a calculator to determine the precise area to be covered.

Why You Need to Know the Wallpaper Quantity and Price

The length and breadth of the roll will be the major determinants in determining how many rolls of wallcovering you need.

Nevertheless, you must also consider cutting around obstructions like windows and doors and evaluate the pattern repetition, particularly the diagonal pattern recurrence.

Always read the product specifics since the width and length may differ. Additionally, some of the more costly premium wallpapers allow you to purchase rolls by the meter instead of rolls per roll, which reduces waste and costs.

Wallpaper Basics & Applications

The essentials that you will need for wallpapering are:


Use a wallpaper quantity and pricing calculator after measuring the coordinates of all your walls to make sure you buy enough rolls. The repeating pattern and other pertinent information will be included in your wallpaper. This dimension indicates how far down the roll the pattern will once again line up.

These specifics are necessary to determine how many rolls you’ll need.

Wallpaper adhesive

If you need to wallpaper in phases, save time and money using ready-mixed wallpaper paste that comes in a reusable container.

A brush for applying wallpaper.

Select a comb with a handle in the center instead of a comb that resembles a large one. Your wrists will like it since they easily fit into pre-made paste containers.

A gauge for measuring plumb lines

If you want to do a lot of wallpaper, they are a terrific investment and are available at DIY shops. On the other hand, if you only need to build a single feature wall, you may download a plumb line measurement app for free on your smartphone.

A pair of sharp scissors and a trimming knife for wallpaper

 Although cutting wallpaper with a knife is simpler, scissors work better for pieces of material that won’t cut since they are wet from adhesive. The scissors are also required to cut the paper off the roll.

Types of Wallpaper

The major types of wallpaper include:

Wallpaper with lines

This wallpaper is made of fiberglass or paper and is frequently known as liner paper. It may cover wall imperfections, save maintenance expenses, and form a foundation for more fragile wallpaper types. It might also be embellished and used on its own and is quite easy to put on and take off.

Printed wallpaper

This kind is frequently used and is available in a broad range of hues and patterns. Although it is more prone to ripping than manually printed wallpaper, the custom-printed wrap may be mass-produced and is sometimes less costly. The printing ink should not be used in restrooms or kitchens as it is water-based.

Vinyl wall art

This kind of wallpaper is made of a paper sheet with many layers of vinyl. It is now the most popular wallpaper due to its outstanding durability. The density of the vinyl coating layer will affect how long the wallpaper will last. Vinyl paper is suitable for use in bathrooms and kitchens as it can withstand steam. It is also simple to keep since it is washable.

Metallic wall decor

A high gloss foil is a base for this design, giving the interior space a glittering metallic look. Foil wallpaper’s high reflectivity makes wall imperfections more noticeable. Therefore, the base wall must first be fixed, cured, or covered with lining paper. The coating and adhering process must be exact to maintain the foil’s gloss and brilliance.

Stylish Wallpaper Options for Every Room

Stylish wallpaper options for every room include:

Ideas for Floral Bathroom Wallpaper

Repeated bathroom wallpaper designs with a floral motif give the space rhythm and motion. Such wallpapers may create a feature wall and give the bathroom a rich, zen-like atmosphere.

Dramatic Backsplash Shots

A backsplash may undoubtedly stand out if the wallpaper has a strong design. Choose a performance wallpaper that can survive the rigors of cooking and cleaning, but only barely.

An Exotic Relationship with Fruits and Flowers

Fruity designs on modern kitchen wallpaper give the room a tempting appearance. Incorporating large-scale artwork can also give your kitchen design a cheerful appearance.

Spectacular Dividers

You may define space by covering and separating walls between open areas with striking living room wallpaper. For instance, this striking black-and-white pattern creates a strong visual distinction between the sitting room and the area that serves as the kitchen bar.

How to Estimate How Much Wallpaper You Need 

You can estimate how much wallpaper you need through the following steps:

  • Determine the width of your wall(s), considering any doorways, windows, and recessed areas. After that, divide that number by the intended purchase’s wallpaper roll’s width. Using this number, calculate how many pieces of wallpaper you’ll need for your room.
  • Calculate the elevation of your room and add 15 cm to allow for trimming at the top and bottom. Add this amount to your height measurements if your wallpaper has a repeating pattern.
  • After calculating the height, divide the thickness of the wallpaper roll by the determined height. By looking at this number, you can find out how many drips there are in a wallpaper roll.
  • Calculate how many complete drops you will obtain from a roll by dividing the number of drops required for your room. You will obtain the entire number of rolls you have to order if you round this number up.
