Quilting charts, quilting formulas and other quilting online tools

This list isn’t comprehensive but a collection of some of the most useful quilting charts, formulas and online tools to help you design your quilts. If you know of other tools, charts or formulas please add a comment.

Quilt sizes and quilt backing fabric

Christen from I see stars quilting has put together this fantastic guide to help us work out:

1. the quilt size you need for a particular mattress size
2. how much fabric you need and
3. how to piece it

Not only she has made this chart but she also tells us all about backing your quilt. Visit her site for details.

Binding calculator

Not a chart but this binding calculator helps you work out how many strips you need for a quilt and how much fabric to buy.

Inches to centimetres conversion

A table but also an online calculator that will convert between inches, yards in decimal form, yards in fractional form, and centimetres.

How many blocks in a quilt

Make Modern Magazine made this very useful chart that shows you how many blocks you need to make a quilt based on block size, with or without sashing.

Precut fabric sizes

• Mini charm: 2.5″ x 2.5″ – 6.35cm x 6.35cm
• Charm squares: 5″ x 5″ – 12.7cm x 12.7cm
• Jelly roll: 2.5″ x 44″ – 6.35cm x 112c
• Jolly bar: 5″ x 10″ – 12.7cm x 25.4cm
• Layer cake: 10″ x 10″ – 25.4cm x 25.4cm
• Fat eighth: 9″ x 21″ or 11″ x 18″ – 22.86cm x 53.3cm or 28cm x 45.7cm
• Fat quarter: 18″ x 21″ – 45.7cm x 53.3cm
• Half yard: 18″ x 44″ – 45.7cm x 112cm
• One yard: 36″ x 44″ – 91.4cm x 112cm

There’re many ways to use precuts.

Some patterns are written for precuts white others, particularly the larger precuts, often are cut into smaller sizes.

Most often it’s fat quarters. Patchwork posse has a very good article on cutting a fat quarter into different sizes with different options.

Also this chart shows you how many squares of a particular size you can cut from a fat quarter.
