New Online Knitting Tool: Waist Shaping Calculator

Mar 27, 2008

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:

The Knitting Daily Online Waist Shaping Calculator!

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:

Waist Shaping: An Overview

Waist Shaping: From Hem to Hip

Waist Shaping: From Hip to Waist

Waist Shaping: From Waist on Up!

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!

Sandi Wiseheart was the editor of Knitting Daily.

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.

Can you please tell me how to switch to cm instead of inches????

20 stiches pr 10 cm is NOT the same as 20 stiches per inch ;)

Otherwise ii is a nice tool :)

The Northern Dreams Pullover by Julia Vaconsin is a perfect winter sweater. I love the colorwork yoke

Sandi, I am about to knit an Alice Starmore Fiarisle pullover and I am going to shape the waist. I will have to be carefull not to mess up the pattern. I wore an AS pullover today. I had modified the armholes to get rid of the bulk and made it a high V pullover instead of a cardigan. However when I looked at it today I decided that an additional improvement would be to update the look by shaping the waist. I will try this on the next AS design. I will let you know how it comes out. KM

What a great idea! The waist shaping calculator is so simple. Thanks to those of you who spent priceless time to create it. How can I have accessibility all the time. I am a certified crochet teacher and I design and sell one-of-a-kind crocheted sweaters. The calculator has made my desiigning more enjoyable. I always hated math! Thank you, thank you.

I do believe that this calculator should have been out much sooner and the fact that it does all the work for you is even better.

I keep getting an error message. I know the measurements are correct. Why do I keep getting this message?
Error Calculating Measurements
It appears that some of your measurements are off and resulted in an math error.

Hi knitting daily folks,

The waist shaping series has been fantastic, thanks! Is it possible to do something similar on sleeve-and-sleeve-hole shaping? All the different shapes and shoulders, so confusing, not to mention how to make them fit together... Thanks heaps! :)

I like the calculator but it would be nice if it gave calculations for working flat also. I always get 'decrease every 3 rows.' That would mean alternating between the right and the wrong side. Any suggestions?

This is great! That will solve my waist length issure. Is there an easy way to alter the measurement from your shoulders to your bust? Like adding a torso length measurement into it? I have scoliosis, which makes my waist almost even with my rib cage and a shorter length to my shoulders. I tried on tops the other day, and on almost every one of them, I can pull the shoulders up 1-2" above my shoulders and see how the shirt is supposed to fit, but they never fit me right.

Thank YOU! I just began a cotton shell and did most of the calculations for the waist shaping from your wonderful instructional e-mails. Your Waist Shaping Calculator validated that I had done the calculations correctly! Much easier using your program than paper and pencil! Now back to my needles! Your tutorials allow me to be a fearless knitter.
