How to Knit a Helpful Swatch – Part 1 Gauge

First, a definition: A Helpful Swatch is a swatch that gives you, the knitter, information that helps you in the planning, preparation and construction of your knitting project. It tells you a number of things that are essential for successful completion, among them:

  • Your stitch and row gauge with the yarn and needles  you have selected for your project
  • The type of fabric produced with your yarn and your gauge.
  • What happens when the yarn is washed and dried.
  • What adjustments are needed to make a garment that fits the way you want it
  • How a given stitch pattern looks when knitted using your selected yarn.

In addition, you can use your swatch to test out different techniques such as decreases or increases that you might want to use during construction. Full disclosure here: You’ll need to knit more than one swatch to get a helpful swatch. This is why most experienced knitters will tell you that you should buy an extra skein of yarn just for swatching.

One of the first issues new knitters encounter when doing a swatch is not knitting a big enough swatch  — they tend to cast on only enough to knit a 4 inch square. In most cases, this isn’t big enough to provide helpful information.  So, how big does a swatch need to be? The short answer is: Big enough to get a good sense of how the project will knit up. Elizabeth Zimmerman wrote that “a hat is a good swatch” – which is true if you are planning to knit your sweater in the round. Some knitters use a sleeve as their swatch, others knit a swatch that is at least 6 inches wide by 6 inches high. I would say that the 6 X 6 swatch is a good starting point – but you made need to make one that is even wider.

GAUGE: Here’s one inescapable truth about yarn, needles, and gauge: “Your Mileage May Vary”.  Meaning that gauge is a very personal thing – it’s yours and yours alone. It is a measurement of the fabric YOU produce when you knit. So doing a swatch to identify your gauge is important to your success.

Before you start your first swatch you need to decide what size needle works best for the project. Yarn labels usually have a recommended needle size and gauge listed. Some manufacturers state a range on the label, others use a symbol to indicate the recommended gauge. Either way, this is just the starting point. A pattern may also include information about the yarn, needles and gauge the designer used to create the pattern. Both sources provide you with a starting point for selecting the size needle you need to use to obtain the knitted fabric you want to make.

Here are the steps I follow to make a Gauge Swatch:

  1. Select 3 sizes of needles – if the recommended needle size on the yarn label is a US 7, I use a US 6, US 7, and US 8 for this swatch.
  2. Cast on enough stitches on the smallest needle size for a width of at least 6 inches. (To estimate the number of stitches to cast on, I use the recommended gauge on the yarn label. For example, the label states 20 stitches in 4 inches, that’s 5 stitches  per inch, so I’d cast on 30 stitches for 6 inches.). Knit in stockinette stitch for at least 3-4 inches ending with a right side (knit) row.
  3. Knit the wrong side row to indicate where the change in needle size occurs.
  4. Change to the US 7 and knit in stockinette stitch for another 3-4 inches.
  5. Repeat steps 3 & 4 with the US 8. Bind off loosely. (You can also just put the live stitches on waste yarn).
  6. Take stitch and row gauge measurements for all needle sizes and make note of these before blocking per step 7.
  7. Block this swatch using the care instructions on the yarn label.
  8. Once the swatch is dry, take stitch and row gauge measurements for each needle size and write them down in your project notes. These are your “finished gauges”.
  9. Select the needle size by looking at the fabric produced by each size needle. Which one gives you the best fabric? Do you like the stitch definition? Do you like the way it drapes and feels? Is one better than the other two? It’s your choice – but this helps you select the needle that works best with you and your choice of yarn.

Measuring the Swatch for Gauge:

Stitch gauge is expressed as “number of stitches in number of inches (or centimeters)”. You may see this as “20 sts/4 in (10cm) or 5 sts/in.  To determine your stitch gauge you need to count the number of stitches in a horizontally measured row of stitches. This measurement should be taken using a ruler and marking the starting point and ending point away from the edges.

Row gauge is expressed as “number of rows in number of inches (or centimeters)”. You may see this as “28 rows/4 in( 10cm) or 7 rows/inch. To determine your row gauge you need to count the number of rows in a vertically measured column of stitches. Again, the measurement needs to be taken using a ruler and away from the top and bottom edges of the swatch.

Note that it is not necessary to measure just 4 inches horizontally or vertically. If you measure more than 4 inches, you may get a more accurate gauge because it will give you a better average – yes – gauge is actually the average number of stitches or rows per inch. And, math is required to determine gauge.

There are any number of YouTube videos available on measuring gauge swatches to determine stitch and row gauge. I recommend the following ones for more detailed explanation:

Master Hand KnitterMaster Hand Knitter

2025 was a year of focused effort toward completing the Master Hand Knitter certification program curated by The Knitting Guild Association (TKGA.org). TKGA is a group of highly experienced knitters who work to help others learn and improve their knitting through various correspondence courses, certification programs, online conferences, in-person conferences and online reference materials. They publish an online magazine, Cast On, quarterly. A yearly membership is $35 and is well worth the price – giving you access to a wide range of resources and expertise.
The Master Hand Knitter certification program is a guided mastery learning program. One achieves mastery through a guided self-study process that includes improving various techniques through practice, learning to research and judge your work and applying new skills. You submit your work and it is reviewed by a group of Master Hand Knitters. You receive a written evaluation of your work along with suggestions on how to improve your work where it did not meet their standards for proficiency.

There are three levels in the program:
Level 1 focuses on basic skills such as determining gauge, making increases and decreases, and knitting some basic stitch patterns.
Level 2 focuses on finishing techniques. It covers different cast ons and bind offs and different methods for seaming and finishing.
Level 3 focuses on designing knitwear and pattern writing. Includes work on advanced techniques such as double knitting, entrelac, brioche, slip stitch and mosaic patterns.
Each level includes completing at least one project demonstrating the skills covered in the level.

 

This program is a journey – not a race. But it was, for me, a wonderful learning experience and a proud accomplishment. I achieved my certification as a Master Hand Knitter in August 2025.

Master Knitter Level I – Swatches #4, #5, & #6 – IncreasesMaster Knitter Level I – Swatches #4, #5, & #6 – Increases

Swatches 4 through 6 in the Master Knitter Level I program are all about increases. Specifically, each swatch demonstrates a particular type of increase. The increases are done on each side, with three stitches before the right edge increase and three stitches after the left edge increase.

Bar Increases

Swatch 4 - Bar Increase

Swatch 4 demonstrates the Bar Increase. This is probably the increase most knitters first learned to make when knitting. It often written as “KFB” in patterns — which means “Knit in the front and back loops”. When you knit into the front loop of a knit stitch and then knit in the back loop of the same knit stitch, the resulting increase has a purl bump where the second stitch was made. It is clearly visible as you can see in this picture.

I learned a few things working on this swatch. Since I am now much more aware of my tension, I found that the purl bumps looked much better if I made certain I kept the tension even with both stitches. It’s much the same issue as when I had trouble getting even tension in ribbing.

Also, through my research, I learned that you should never make your increases on the very edge of your knitting — you should have at least one stitch on the edge before doing the increase. This makes it much easier and neater to do seams. This is something to pay attention to when you are knitting pieces that will be sewn together — I know I will practice this in my future knitting projects.

Swatch 5 - Knitted Make 1 Increases

Swatch 5 - Make 1 Increases

Swatch 5 demonstrates Make 1 increases. On the right edge, I knit an M1R increase — which means “Make 1 Right” — this is a right-slanting increase. It is made by inserting the left needle from the back and lifting the horizontal strand between stitches onto the left needle and knitting into the front of this strand.

On the left edge, the increase is an M1L — which means “Make 1 Left” — a left-slanting increase. It is made by inserting the left needle from the front and lifting the horizontal strand between stitches onto the left needle and knitting into the back of this strand.

M1 increases are tighter and there is no purl bump on the front of the knitting.

Swatch 6 - Lifted Increases

Swatch #6 - Lifted Increases

Swatch 6 demonstrates the Lifted or Raised Increase. This is the most invisible of increases — and was an increase I had never used before, so the entire swatch was a learning experience.

Again, I knit a right-slanting increase on the right edge. This increase is done by lifting the stitch below the stitch on the left needle and knitting it.

The left-slanting increase on the left edge of the swatch gave me the most difficulty. I had to search out several different pictures of it in my references before I figured it out. The left-slanting lifted increase is done by lifting the stitch below the stitch just knitted on the right needle and then knitting it.

The best pictures and explanations I found of this increase, as well as the others, were in an online article at Knitty.com, entitled “Techniques with “Theresa – Increases”.

So, these three swatches improved my technique when knitting increases and I learned a method of increasing that I had never used before. Check out the article on Knitty.com if you want to explore these methods.

Progress on Socks for SoldiersProgress on Socks for Soldiers

I am making progress on my first pair of “regulation socks” for Socks for Soldiers. It has been slow going. I had knitted about four inches in 2 x 2 ribbing when I decided that I had an issue with laddering. Usually when you knit on two circulars, you don’t have a problem with ladders developing between the needles – but there they were… I figured out that I was causing the problem by tugging too hard on the yarn when I knit the first two stitches on each needle. The Regia Stretch yarn is really stretchy and because I was pulling the yarn too tightly I had ladders. So, I made a trip to the frog pond and frogged the socks all the way back to the beginning. (Sigh…)

9 inches of sock leg.

9 inches of sock leg.


Well, I now have 9+ inches of leg done on both socks. The first 8 inches were knit on size US 2 (3.00 mm) circulars, with a stitch gauge of 8 spi. Following the directions of the official pattern, I switched to Size US 1 (2.25 mm) circulars, which have a gauge of 9 spi. The leg continues in ribbing until it measures 12 inches and then you begin the heel. I’ll post an update when I get to the heel.
