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:
- the quilt size you need for a particular mattress size
- how much fabric you need and
- how to piece it
Not only she has made this chart but she also tells us all about backing your quilt.
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

- 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

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.

I refer to Blossom heart quilts chart frequently to work out my HSTs:
Flying geese chart and formula
This is a video demo of the no waste flying geese. Use the formula below to make the block in different sizes.

Quarter square triangles chart
This video demonstrates how to make a quarter square triangle. Use the formula below to make the block in different sizes and check Bonjour quilts post for more information on the formula.
Set in and corner triangles
This chart is very handy when making a quilt on point.
But what’s an on point quilt?
An on point quilt is assembled in diagonal rows.
Each diagonal row starts and ends with either a corner setting triangle or a side setting triangle.
Julie Baird of Generations quilt patterns has a good in depth explanation on setting triangles for an on-point quilt.

I wanted to share this very special PDF of charts by Deborah Paul that she compiled herself and shared with us. This may be useful as one pager to have handy when working out a design.

My book Turnabout Patchwork
“Turnabout Patchwork. Simple quilts with a twist” is all about playing with blocks – making a block, slicing it up, and turning or repositioning the pieces to make a completely different block (sometimes two smaller blocks) to yield endless quilt tops.
