# Online Knitting Tool: Waist Shaping Calculator

So it’s Friday. It’s Spring. Don’t you think we all deserve a little teensy goodie today? Yup. We do. That’s why here in the Knitting Daily offices, we’ve spent part of this week cooking up a spring surprise for you:

This little wonder widget takes you through the steps we’ve been talking about in our Waist Shaping 101 mini-course and does the math for you! It asks you for all the pertinent information: stitch and row gauge, hip/waist/bust measurements, desired ease, and the necessary vertical measurements, then gives you stitch counts, row counts, and fills in the blanks for such things as “work decrease row every X row Y times.”

A few notes on how to use the calculator:

You can use either inches or centimeters in this calculator–but be sure to be consistent throughout! If you start out entering your gauge in centimeters, then enter all the other measurements in centimeters, too.

You can use either negative ease or positive ease. Put a minus sign in front of the negative ease numbers; enter the positive ease as normal.

Hover your mouse over the little question marks for a definition of that item.

This calculator was designed for bottom-up sweaters. You can also use it for top-down sweaters, provided you remember to flip-flop the increases and decreases. In a top-down sweater, you decrease from bust to waist, and increase from waist to hip; in a bottom-up sweater, you decrease from hip to waist and increase from waist to bust! The calculations are otherwise the same.

Hey crocheters! This same calculator works for you, too!

If you need a reminder as to how all of this works, here are the posts in our Waist Shaping Series that walk you through each step:

So: Enjoy! And thanks to our talented web programmer Jason, who took my pages and pages of notes and turned them into something easy-to-use!

There’s even a couple of buttons so you can easily link to the calculator from your blog or website. Let us know what you think!

What’s on Sandi’s needles? You know how it is. A friend tells you she’s preggers, then invites you over for Easter dinner. Am I the kind of person who can show up without a tiny handknitted baby gift in my hands? No. I am not. Thus, I quickly knitted the most adorable baby jacket ever, the Baby Bolero from the book One Skein.
