Fabric Calculator - Creative Widgets

Starting a new DIY project is always exciting, especially when working with fabric.

When itching to start, you don’t want to waste time calculating how many pieces you need and how to size them.

So here is a simple fabric calculator that tells you all you need. Just fill in your dimensions and get results right away.

Here’s a step-by-step guide:

First, you need to know a few pieces of information:

Fabric width: Fabric rolls come in standard widths, commonly 44-45 inches and 54-60 inches
Dimensions of the pieces: Width and length of the fabric
Number of pieces: How many pieces do you need

When you have this information, follow these steps:

Calculate the number of pieces across:

Pieces across = Fabric Width / Piece Width

Then calculate the number of rows you need to cut:

Rows to cut = Pieces to cut / Pieces Across

Finally, calculate the length of the fabric:

Fabric Length = Piece Length * Rows to cut

This tells us exactly how many pieces you need to cut and what fabric length to buy.

Imagine you have the following project:

Piece Dimensions: You need to cut pieces that are 20 inches in width and 30 inches in length.
Number of Pieces: 4
Fabric Width: 45 inches
Seam Allowance: 1 inch on each side

Let’s calculate rows to cut and pieces across

Pieces Across = 45 in / 20 in = 2.25 pieces = 2 pieces

We will have two pieces across, and also we will have 0.25 inches of leftover fabric.

Rows to cut = 4 pieces / 2 pieces = 2 rows

You will need to cut the material into two rows.

Now let’s calculate the fabric length:

Fabric Length = 30 inch * 2 = 60 inch

So, overall, you will need fabric that is 60 inches long.

There are a couple of things that I think are valuable to mention

Rounding Up: It’s always a good idea to round up to the nearest quarter or half yard to ensure you have enough fabric, especially to account for errors or adjustments.
Pattern Repeats: If your fabric has a pattern, measure the repeat and add this to your total length to ensure the pattern aligns correctly.
