First hat on a loom: what size round loom you actually need

By Hannah Pierce
· 6 min read
How we choose
The answer

Choose a round knitting loom with 36 to 40 pegs for beginner hats. This size fits most adult heads using worsted weight yarn at average tension. Confirm fit by knitting a swatch of 20 pegs and 20 rows, measuring stitches and rows per inch. Adjust peg count or yarn weight if gauge or head size differs. Use a loose e-wrap cast-on to keep edges stretchy and avoid tightness.

The short version

  • Loom shape impacts project type: round for hats, long for scarves.
  • 36-40 peg round looms fit worsted yarn for typical adult hats.
  • Starter kits should include a loom, hook, yarn needle, and loom tool.
  • Use a stretchy cast-on and bind-off to stop edges from tightening.
  • Common first-project issues include tight edges and dropped loops.

Round vs long vs rectangular loom and what each one actually makes first

round knitting loom with pegs and yarn

Round looms with 36 to 40 pegs most naturally make hats sized for adult heads. The circular shape fits the head’s curve, and peg count matches worsted weight yarn gauge well.

Long or rectangular looms usually have 20 to 24 pegs and produce flat pieces, perfect for scarves or flat panels for blankets.

Choosing your first loom shape depends on the project you want. If you want a hat first, pick a round loom. For scarves, long looms are better.

The peg count on these looms directly impacts the circumference of the finished hat or width of a scarf. The other half of this decision is matching project type to loom size.

Peg count and gauge vs yarn weight for a beginner hat and scarf

Worsted weight yarn usually works best with 36 to 40 peg round looms for a beginner hat. This peg count fits an adult head circumference of about 21 to 23 inches (53 to 58 cm).

Using too few pegs with thick yarn makes the hat tight and small; too many pegs with thin yarn makes it loose and baggy.

For scarves, 20 to 24 pegs on a long loom suits worsted yarn and creates a 5 to 7-inch wide (13 to 18 cm) scarf, a comfortable beginner width. We go through knitting kits for beginners step by step elsewhere on the site.

Gauge is the number of stitches per inch your yarn needs, and the loom’s peg spacing usually matches or slightly stretches the gauge for comfort.

  • Hat loom peg count: 36 to 40 for worsted weight yarn
  • Scarf loom peg count: 20 to 24 for worsted weight yarn
  • Gauge depends on yarn and loom spacing
  • First project size depends on peg count and yarn thickness

What a starter kit must include and what you can skip

A beginner’s knitting loom kit should include the loom itself, a loom hook for lifting loops, a yarn needle for finishing, and a loom tool for corrections.

Extra yarn is helpful but usually better to choose your own once you know your gauge and project. For the detail, see our notes on best beginner knitting books.

Some kits add instruction booklets or patterns, which are useful but you can find free tutorials online.

Skip specialty tools like loom weights or tensioners until you better understand your knitting style.

Some starter kits include extra yarn, but you might prefer choosing yarn yourself. This way, you match the yarn weight and color to your project needs. Beginners often pick worsted weight yarn, which works well on common loom sizes.

Instruction booklets are helpful but not required. You can find many free videos and tutorials online that show knitting loom basics clearly. Starting with these saves money and lets you learn at your own pace.

Avoid buying specialty yarns or extra tools like loom weights at first. These can complicate your learning. Master basic knitting and loom handling before adding extras. Focus on understanding tension and stitch control first.

  • Must-have: loom, loom hook, yarn needle, loom tool
  • Nice-to-have: beginner pattern booklet
  • Skip at first: loom weights, tensioners, specialty yarns

Cast-on and bind-off that keeps the edge from going too tight

A stretchy cast-on method, like the e-wrap cast-on, prevents the edge of your hat or scarf from pulling too tight and curling.

Bind-off should also be elastic, often done by gently stretching the edge loops as you finish so the fabric lays flat.

Avoid tight cast-ons or bind-offs that pull fabric inward; these cause discomfort and misshapen projects.

You can watch beginner tutorials online showing these techniques step-by-step before starting.

Some cast-on methods cause the first row to pull too tight, shrinking the hat’s opening. The e-wrap cast-on adds slack by wrapping yarn around each peg twice, creating stretch.

When binding off, pull loops gently to avoid a stiff edge. You can slide loops off the pegs while holding the yarn loose. This keeps the fabric flexible and comfortable to wear.

Try a loose slip knot to start your cast-on. Check your first row by stretching it with your fingers. If it doesn’t stretch, you need a stretchier cast-on or looser tension. This check prevents tight edges and frustration later.

  1. Wrap yarn around pegs with extra slack for e-wrap cast-on
  2. Lift loops gently with loom hook, avoiding tight pulling
  3. For bind-off, lift and transfer loops carefully while stretching edge
  4. Finish by weaving yarn end with yarn needle to secure

Common first-project fails and how to fix them

Dropped loops often happen if the yarn slips during lifting; fix by picking up the dropped stitch immediately with your hook before more unravel.

Tight edges are usually from too few pegs or tight cast-on; switch to a peg count matching your yarn or a stretchier cast-on method.

Yarn splitting is common with some cheaper yarns; try a smoother, plied yarn and slower, deliberate lifting motions.

If your hat turns out too small, count if you used the right peg number and yarn gauge; adjust your loom size next time.

  • Dropped loops: rescue quickly with hook
  • Tight edges: adjust peg count or cast-on
  • Yarn splitting: change yarn or lifting speed
  • Wrong size: check peg count and yarn weight

best knitting loom for beginners

The best knitting loom for beginners is a round loom with 36 to 40 pegs. Brands like Boye and Knitting Board offer models in this range. For example, the Boye 36-peg round loom has pegs spaced about 0.28 inches (7 mm) apart. This spacing works well with worsted weight yarn, which is common for beginners. Expect a finished hat circumference of roughly 21 to 23 inches (53 to 58 cm) if you knit at typical beginner tension. Check the manufacturer's specs for peg spacing before buying, or test the gauge by wrapping yarn around the pegs in a swatch. Measure your head circumference with a soft tape measure at the widest part to ensure a good fit.

Loom kits vary but often include the loom, a hook, a knitting tool, and sometimes extra yarn or patterns. The Boye 36-peg loom kit costs around $20 to $30. Some kits add instruction booklets, which help beginners but you can find tutorials online too. Skip specialty tools like loom weights or tensioners until you understand your tension better. Beginners should focus on mastering the loom basics first.

Check your gauge by knitting a small swatch on the loom, counting how many pegs per inch you cover with your yarn and tension. Compare this to your yarn’s recommended gauge on the label. Adjust your tension or choose a different loom size if needed. A looser cast-on edge helps prevent tightness. Use a single, loose wrap per peg (simple e-wrap), as shown in the Knitting Board tutorial (https://www.knittingboard.com/tutorials/e-wrap-cast-on/). This creates a stretchy edge that fits comfortably around the head.

Round looms with 36 to 40 pegs fit most adult heads if you knit worsted weight yarn at beginner tension. Peg spacing and yarn weight affect the final size. Measure your head and test gauge before you start to avoid surprises. Brands like Boye and Knitting Board have reliable looms in this size range. Check their websites or craft stores for current prices and availability.

The verdict

For a first knitting loom, a 36-40 peg round loom suits beginners best; it matches common yarn gauge and project size.

Still wondering?

Can I use a long loom to knit a hat?

Long looms produce flat fabric, so knitting a hat requires seaming or complex shaping. Round looms are simpler and better for first-time hat projects.

What yarn weight should I start with on a loom?

Worsted weight yarn (medium thickness) is best for beginners because it fits common peg spacing and is easy to handle.

Are wooden looms better than plastic for beginners?

Wooden looms last longer and feel nicer but cost more. Plastic looms work well for practice and beginners on a budget.

What causes the edge of my loom knitting to be too tight?

Tight edges often result from using too few pegs or a cast-on method that lacks stretch. Switching to a stretchier cast-on and correct peg count fixes this.

What if my knitting drops a loop?

Dropped loops should be caught and fixed immediately with a loom hook. Left unattended, they unravel and ruin your project.

I learned on a 36-peg round loom and found it balanced size, yarn, and ease perfectly for my first hat.
