# How Many Rolls of Wallpaper Do I Need: A Guide to Accurate Estimation

*How Many Rolls of Wallpaper Do I Need?*

To calculate the number of rolls of wallpaper needed, multiply the height of the room/area in meters by the number of widths needed.

Then, divide that number by the length of the wallpaper roll (usually 10m) to determine the number of rolls needed.

It is recommended to get a couple of extra rolls, especially if the wallpaper has a repeating pattern.

Unopened rolls can be returned later.

If you need help estimating the number of rolls needed, consult a decorator, especially for rooms with larger pattern repeats or complex shapes.

**Key Points:**

- Multiply the height of the room/area by the number of widths needed to calculate the number of rolls of wallpaper needed
- Divide the previous number by the length of the wallpaper roll to determine the number of rolls needed
- Get a couple of extra rolls, especially for wallpaper with a repeating pattern
- Unopened rolls can be returned later
- Consult a decorator for help estimating the number of rolls needed, especially for rooms with larger pattern repeats or complex shapes.

**Did You Know?**

1. On average, a standard roll of wallpaper measures about 21 inches wide and 16.5 feet long.

2. The number of rolls needed to cover a room with wallpaper depends on the dimensions of the room and the size of the wallpaper pattern. A general rule of thumb is to divide the total square footage of the walls by the square footage coverage of each roll.

3. Wallpaper rolls traditionally used to have a standard length of 10 yards (or 30 feet). However, in recent years, some manufacturers have introduced longer rolls measuring up to 33 feet.

4. When calculating the number of rolls needed, it is essential to consider the pattern repeat of the wallpaper. The pattern repeat is the vertical distance between the spots where the pattern will align perfectly.

5. It’s always a good idea to account for extra rolls when purchasing wallpaper. This allows for mistakes, repairs, or future touch-ups. To be safe, it’s recommended to buy at least one or two additional rolls beyond the calculated amount.

## Calculating The Number Of Rolls Needed

Estimating the number of rolls of wallpaper needed for a room can be a daunting task. However, with a simple calculation, you can determine the exact quantity required, ensuring you have enough to complete the project seamlessly.

To start, multiply the *height* of the room or area in meters by the number of *widths* needed. Then, divide that number by the *length* of the wallpaper roll, which is typically around 10 meters. This will provide you with the number of rolls needed to fully cover the desired space.

*Example calculation:*

- Height of the room = 3 meters
- Widths needed = 4
- Length of wallpaper roll = 10 meters

Calculation: (3m * 4) / 10m = 1.2 rolls

So, *approximately 1.2 rolls* of wallpaper would be needed to cover the room.

Remember to consider any additional factors such as pattern matching and waste allowance, which may require additional rolls. Happy decorating!

## Example Calculation

Let’s consider an example to illustrate the calculation process. Assume we have a room with a **height of 2.4 meters** and a **room width of 19.2 meters**, with a **wallpaper roll width of 0.52 meters**.

To find the number of rolls needed, we multiply the height (**2.4m**) by the room width divided by the wallpaper roll width (**19.2m ÷ 0.52m**).

The result is **46.08**. Thus, we would need approximately **46 rolls of wallpaper** to cover the entire room.

## Getting Extra Rolls

When **purchasing wallpaper**, it is always recommended to acquire **a couple of extra rolls**, especially if the wallpaper has a **repeating pattern**. This precautionary measure ensures that you have enough material to accommodate any **mistakes**, unforeseen obstacles, or pattern matching. Moreover, having **spare rolls** guarantees that you can continue the project seamlessly if any replacement is required in the future. This extra precaution will save you from potential **delays or difficulties** in finding an exact match later on.

## Frequently Asked Questions

### How do I calculate how many wallpaper rolls I need?

To determine the number of wallpaper rolls needed, start by measuring the height of the room or area in meters. Multiply this height measurement by the number of widths needed for the desired coverage. This calculation gives you the total area of wallpaper required. Next, divide this number by the length of the wallpaper roll, typically 10 meters, to determine the number of rolls needed for the project. By following this formula, you can accurately calculate the quantity of wallpaper rolls required for your desired coverage.

### How much wallpaper does 2 rolls cover?

Two rolls of wallpaper can cover a significant amount of space. Since a double roll generally covers around 57 to 61 square feet, it means that two rolls would cover approximately 114 to 122 square feet. On the other hand, a single roll usually covers around 29 to 31 square feet, so two rolls would cover approximately 58 to 62 square feet. The exact coverage will depend on the specific width of the wallpaper sheets, but with two rolls, you can transform a decent-sized area with a fresh and stylish look.

### How much wallpaper is usually in a roll?

The amount of wallpaper in a roll varies depending on the size of the roll and the dimensions of the room being decorated. Typically, a standard-sized wallpaper roll measures around 50cm or 52cm wide and 10m long, covering approximately 5 or 5.2 square meters. This quantity of wallpaper is generally sufficient for three to four vertical drops in an average-height room, enabling a decent coverage for the space.

### How much wallpaper paste for 1 roll?

Typically, to ensure optimal coverage, it is recommended to use 1kg of wallpaper paste for a single roll of standard wallpapers. However, it is crucial to consider the wall surface condition and the type of paper being used. For instance, heavily embossed papers may require a larger amount of adhesive to properly adhere to the wall. Therefore, it is essential to assess these factors carefully to determine the appropriate quantity of wallpaper paste needed for each roll.
