Enter the length and width of the bed and the margin into the calculator to determine the blanket size.

## Blanket Size Formula

The following formula is used to calculate the size of a blanket.

BS = (L + 2M) * (W + 2M)

Variables:

- BS is the blanket size L is the length of the bed W is the width of the bed M is the margin for the blanket to hang over the sides of the bed

To calculate the blanket size, add twice the margin to the length of the bed and to the width of the bed. Then, multiply these two results together to get the total blanket size.

## What is a Blanket Size?

A blanket size refers to the dimensions of a blanket, typically measured in inches or centimeters. The size can vary greatly depending on its intended use. For example, a throw blanket for a couch may be smaller, while a blanket for a king-sized bed would be much larger. Common blanket sizes include twin, full, queen, and king, corresponding to standard bed sizes. However, the exact dimensions can vary slightly between manufacturers.

## How to Calculate Blanket Size?

The following steps outline how to calculate the Blanket Size using the given formula:

- First, determine the length of the bed (L).
- Next, determine the width of the bed (W).
- Next, determine the margin for the blanket to hang over the sides of the bed (M).
- Next, substitute the values of L, W, and M into the formula: BS = (L + 2M) * (W + 2M).
- Finally, calculate the Blanket Size (BS).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge:

Length of the bed (L) = 80 inches

Width of the bed (W) = 60 inches

Margin for the blanket to hang over the sides of the bed (M) = 10 inches
