Gauge

How do you make sure that you project will come out as directed? Check the gauge before you start! This is the one place in knitting that you should not take a shortcut with. Because everyone knits differently, the gauge of the loom is not that important. If you knit tighter or looser than the author does, your project will not come out the same. Many different things can effect the gauge including stitch pattern, yarn, color of yarn and even your mood. There are times when you may be able to get away with not knitting a swatch but only if the project does not need to fit perfectly, e.g., a blanket, shawl, etc. But when size is crucial, it's not worth taking the chance. Blocking can correct some gauge problems but there is no gaurantee. It's easier to know the gauge upfront and change the pattern accordingly instead of trying to fix it afterwards.

So exactly what is gauge? Merriam Webster defines gauge as:

The fineness of a knitted fabric expressed by the number of loops per unit width.
To determine the gauge, you need to knit a swatch. It may seem tedious and boring but once you understand its importance, hopefully you will not think of it that way.

How important is the gauge? If you are off just 1/2 stitch per a couple of inches and are making a fitted item, it won't fit. Don't learn it the hard way, by spending a lot of money on that beautiful yarn and knit a sweater for yourself just to have to give it to someone else. Knit the swatch!

  • Type of pegs: If you work up a swatch with metal pegs, don't change to nylon or rubber and expect the same gauge, even if you use the same gauge loom.

  • Your mood: It's best not to knit a swatch when you're tense or upset or your knitting will be much tighter.

  • Yarn color: Due to the color dying process, yarn of different colors, even from the same brand, can be different.

  • The weather: Much like it effects your joints, the weather also effects your yarn. Humidity and barometer changes make the yarn expand and contract. You may not think by much but by enough to change the gauge. So, if your weather is different than normal for your area, don't knit a swatch that day, work on something else instead.
  • The more experience you have as a knitter, the better you will be able to judge the the gauge loom and number of stitches you'll need for four inches across. Until you've had enough experience, use the label on your yarn as a starting point. Remember that knitting swatches is not an exact science — play around and have fun. If you start to get bored, use your imagination with the swatch and think about how your final project will look.

  • Start and end the swatch with 4-6 rows of the garter stitch and knit 2-4 stitches at the beginning and end of each row. You want your swatch to stay as flat as possible for measuring and if you don't put on this border, there's a good chance that your swatch will roll.

  • It is best to knit at least 6 inches squared of the stitch in your chosen pattern. While some manuals will suggest 4, the larger the swatch, the more accurate gauge you will have.

  • The loom gauge noted in the pattern is a good place to start for figuring out which loom to use but do not get married to it. The more you knit, the better idea you will have of how your knitting compares to what is noted in patterns and which loom gauge (+/-) will work for you. Remember that which type of peg you use on your loom will effect the gauge. Knitting with metal pegs, nylon pegs and rubber pegs may all come out differently even if the loom gauge is the same.

  • Once you've knitted your swatch, check the area on the pattern that states the gauge. If you do not come out with that number of stitches per inch, you will need to reknit the swatch with a different loom gauge or possibly with different pegs. Rule of thumb: too few stitches per inch, use a smaller gauge loom; too many stitches per inch, use a larger gauge loom. Do not frog the swatch and reuse it to knit the new swatch or the gauge will not come out accurately (see below).

  • Measuring should happen only after you bind-off, not while on the loom. Your stitches will be distorted if you leave your work on the loom.

  • Don't frog the swatch to reuse in your project or on a new swatch. It will be stretched and will knit differently. Instead, safety-pin a tag on it with the project, label of the yarn and other swatch information and store it in a box for later use.

  • Use your swatch to test finishing and blocking techniques. This will give you a true picture of the gauge for the final project.

Tips for Measuring

First and foremost, it's important to measure carefully when determining the number of stitches per inch. Here are some ways to make sure that you do.

  • Place your work on a hard, flat surface. For example, do not put it on a paperback book on your lap to measure the swatch.
  • Do not use a measuring tape. Instead use a plastic, wooden or metal ruler. Better yet, buy a knitting gauge rule. They are not expensive and are easy to use.

Determining the Gauge

To figure out the gauge, count the number of stitches across several inches and then divide the number of stitches by the number of inches. It's OK to end up with decimals. The more accurate you can be, the better. Here are two examples:

  • If your swatch is 4 inches wide and there are 20 stitches across, you'd have a gauge of 5 stitches per inch.
  • If you swatch is 4 inches wide and there are 14 stitches across, you'd have a gauge of 3.5 stitches per inch.
The gauge of the loom is part of the equation for the gauge, in the same way as the size of the needles are. However, since each person knits differently, one person could use an ESG loom and another a FG loom and both of their knitting could be the same gauge. To help you get started in figuring out which gauge to use for your patterns, use the tabs on the left for three common manufacturers: Provocraft Knifty Knitter, In the Attic, and Decor Accents, Inc. More loom manufacturers will be added in the future. Loom gauge is not standardized so please be sure to check with your manufacturer to see both how they measure gauge and what their gauges are. Remember, though, that your own knitting style will ultimately decide which gauge loom you should use for the knitted piece. For more information on this, see section on yarn.

All of the looms noted here were measured from the center of one peg to the center of the next peg.

Provocraft's Knifty Knitters are the most commonly used looms today. Below are the gauge measurements for each of their looms. All of these looms are considered large-to-extra large gauge in size and have an approximate US 10-13 equivalent needle size. General yarn recommendations are for a tight stitch are

  • 1 strand of Super Bulky (6)
  • 1 strand of Bulky (5)
  • 2 strands of Medium (4)
In addition, you can use 1 strand of Medium (4) weight yarn with the flat or knit stitch on looms with a gauge of 11/16" or smaller and have a nice tight stitch.

Looms that can be used as a knitting board have the pegs on each side of the board noted.
