## What is QuiltingCalc?

Robert Kaufman Fabrics and Quilter's Paradise have joined forces to bring you a collection of eight essential quilting calculators.  

With these calculators you'll be able to quickly convert between yards and inches, meters and centimeters; learn how much fabric you need for backing, batting and borders; and determine how many rectangular pieces can be cut from a larger piece. There are even calculators for square-in-a-square, set-in and corner triangles.

Here's a brief description of each calculator:

Fabric Measurement Converter:  Converts between inches and yards in decimal form, and yards in fractional form. (With metric equivalents.)
  
Backing and Batting Calculator:  Determines how much material from a bolt of fabric is needed to make the backing for a quilt. 
  
Piece Count Calculator:  Shows the number of fixed-sized pieces of fabric that can be cut from a larger piece. 
  
Pieces to Area Calculator:  Indicates how much fabric is needed in order to cut a given number of fixed-sized pieces. 
  
Binding Calculator:  Tells you the amount of fabric required to bind your quilt, based on the quilt’s dimensions and the binding strip width. 

Border Calculator:  Shows the amount of fabric required to create borders, based on a quilt’s dimensions and the width of the borders. 

Square-in-a-Square Calculator:  Works out the key dimensions of a square-in-a-square block.

Set-in and Corner Triangle Calculator: Determines the size of the square piece you’ll need to cut in order to create both unfinished set-in triangles and unfinished corner triangles.

### 5/5 — Best calculator for quilt projects

*2026-08-24, version 8.0.1*

Use this app all the time. Had never let me down.  Suggest it to all my students

### 5/5 — Great app

*2026-02-26, version 8.0.1*

Wouldn’t be without this app, a must for anyone that not too great on maths. I have used it so many times with success

### 2/5 — Used to be so good

*2026-01-21, version 8.0.1*

This calculator app is buggy. Ages ago, I used to love using this app but when calculating for multiple quilts, I have to exit the app because it won’t go back so I can put in new measurements or put in measurements for a different field. It’s so frustrating.

### 2/5 — Trouble with site

*2025-10-30, version 8.0.1*

I have had a problem with this app all day and I never have before. After entering the measurements required, when I tap calculate, it says something to the effect that I need to enter a number in the width. First, I don’t know if it means width of fabric or width of quilt. There are numbers in both places. I really like this site but I’m very frustrated with this issue. I hope you can fix it.

### 3/5 — Updates

*2025-09-01, version 6.0.1*

Since the update I keep getting fabric width must contain a number or border 3 needs to have a numeric number.  Ugh!!! There are numbers in the field and I don’t want 3 borders. Please fix this issue.

### 5/5 — Fabric calculator

*2025-08-18, version 5.7.18*

Where do I find the RK calculator

### 1/5 — Back button doesn’t work

*2025-03-13, version 5.7.18*

When you go to a topic the back button  “<“ doesn’t work. You have to close out and go back in again

### 5/5 — Great app

*2025-03-07, version 5.7.18*

I’ve used this app for years and find it very helpful. Thanks to Robert Kaufman for making it available!

### 5/5 — Useful!!

*2024-12-31, version 5.7.18*

I use this app for every quilt. No more cutting too much or too little binding or borders. Wonderful calculator. Thank you very much.

### 1/5 — Ok when it works

*2024-12-27, version 5.7.18*

I use this app frequently. But, many times I will open it up and it’s blank. Unable to get into it at all. So I have to remove it, turn my phone off, reboot it, and then reload the app. I’m having to do that more and more frequently.
