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.

A couple of conveniences

This is my “go to” app for calculating fabric needed, especially for borders and bindings. I make between 5-10 quilts each month for Project Linus. There are two improvements I would like to suggest:
(1) I always use 2.5” strips to bind. Wouldn’t it be nice to be able to set that as a default (with the option to change, of course) instead of having to manually insert that preference each time?
(2) The same for borders. I almost always use non-miter borders. I can’t tell you the number of times I cut an additional strip because I neglected to change the calculation parameters to non-mitered from mitered (which is the default).

Two minor tweaks would make this girl a very happy quilter.

Please provide landscape mode/iPad version

This app has been very handy for me. I haven’t found the miscalculation some have reported, although if you really want to save every inch it might be a bit generous. However, I have an iPad in my sewing room that’s on a stand in landscape mode mode which I use for viewing PDFs while sewing, etc. When I want to use this app I’ve got to unplug it and rotate which is cumbersome and inconvenient. I also took a star off because there are some typos in the text, some of which are just grammatical and can easily be ignored, but some are confusing, such as combining inches and centimeters in the same explanation (eg, in the discussion of how backing is calculated they add an overage of 4 cm to a quilt measured in inches). It’s obvious the writer meant inches but these things should be caught in proofreading.

So, 4 stars for the iPhone, but 2 for the iPad.

Really like this app

I've been using this app for over a year and really like it for quickly calculating binding and borders.
It has not cut me short on yardage calculations, if anything estimates a bit on the plus side which is not a problem for me.
I would miss it because it's my go to now rather than the old calculator.
Quick and easy to use.
