I am excited to introduce a new quilting tool to you today, the Equilateral Triangle Quilt Calculator. When piecing equilateral (60°) triangle quilt tops, it can be hard to know what size your quilt top is going to finish. With this spreadsheet based tool, you can now determine just how large your quilt top will finish! You can get to the tool by clicking on the Triangle Quilt Calculator link in my menu bar at the top of my page.

I put together a quick video tutorial about how to use the tool. I hope it is a useful resource for the quilting community!

Linking up with Main Crush Monday.

    Yvonne, thank you so much for the
    great tool! I have been wanting to make
    A 60 degree quilt and even bought a
    ruler but wasn’t sure of finished size.
    I tend to just start putting pieces together then checking for size. Sometimes it works and sometimes it doesn’t. I know your formula will help.
    Thank you!

    Much easier than playing with trigonometry equations or winging it! Thanks!

    This is awesome!!!! Thank you Yvonne!

    Thank you! This is excellent!!!

    Very handy to have this tool, and thank you for developing it and providing it to the quilting community.

  7. Yvonne, this is a wonderful tool! I have been contemplating a E. T. quilt for awhile, but most likely will not get to it until next year. Thank you for sharing and have a wonderful creative day!

    Good tutorial. Thanks for sharing.

    Such a cool tool, I’ll have to remember it before I embark on a triangle quilt! Thanks! :)

    Thank you, its always a bother when you want to put a quilt on point, I sit there thinking what about the setting triangles etc and give up. So there goes my creativity, hahaha, cheery bye Tina

    Oooh, this will be fun to play with! I suddenly feel like maybe I should make a HST based quilt for my sister ;-)

  12. Heather says:

    My brain would just shut down if I ever attempted to calculate a quilt size using triangle blocks. Thank you for sharing this!

  13. Jasmine says:

    Thanks, Yvonne! I love quilts math, but haven’t made a triangle quilt yet. (Although a ruby quilt and a tree quilt are both on my bucket list.)

  14. Apparently if one throws their quilty wishes out there into the blogosphere, they will come true! Time to write a post about my dream to be sponsored by Kona! :)

    This will make life so much easier – I was always terrible at math, but better with geometry. You have just eliminated so much math from my life. We get better at something that we use all the time, but the child in me says “I don’t want to do the math, I just want to to play!”
    Thank you for letting me just play!

    What an awesome tool, Yvonne!! I have only ever made one ‘normal’ equilateral triangle quilt and it was amazing to see how much those rows shrunk once I started sewing them together!! I will definitely be doing another triangle quilt and I’ll definitely be using your tool!!Thanks!!

    Thank you taking the time to create this! I am pinning it for future reference. I have yet to do a triangle quilt but I love them.

  18. Great little tool! I really loved making my last triangle quilt and need to make another so this will come in handy.

  19. heulwenprice says:

    I do love an equilateral triangle quilt! :D The trig never bothered me that much, but this is so much handier than digging out the calculator and scratch paper, thanks! <3

  20. A triangle quilt is on my someday to do list and you know how I hate to do quilty math! This will be so helpful, thank you! And thanks for linking up to MCM.

  21. I made one a few years ago and it was not at all scientific. I bought four metres of white, cut it up into triangles and alternated the white triangles with scraps until it looked ‘big enough’. This would be far more precise! :)

  22. Jennie says:

    Oh, this is wonderful, thank you! I tried ET once it was a bit of a disaster. I think the uneven sides look really cool too.

  23. Melanie C says:

    This tool is fantastic! Thank you!

  24. sallyqiad says:

    Great tool, many thanks!

  25. sally says:

    You are definitely the tool guru of the quilting blog world!

  26. Terri Ann says:

    I really love this tool! I wish I’d had it when I made my last triangle quilt cause while I took the time to figure out the formula I know I lost that sheet about 12 times and re-calculated the project over and over again second guessing myself. Great work!

I really appreciate the time and thought you take to comment, and I look forward to conversing with you. :)
