Addi Express — Needle-Size Equivalent Reference (Worsted / Beginner)

Short Answer

An Addi Express circular knitting machine has no "needle size" you can change — it uses fixed hooked needles set at a fixed spacing. The closest hand-knitting equivalent, based on the stitch (loop) size it produces with worsted yarn, is roughly:

US 10–11 / 6–8 mm hand-knitting needles

Most makers find worsted on an Addi Express behaves most like 7 mm (US 10.75/11).

Why It's a Range, Not One Number

On a hand needle, the needle diameter sets your loop size. On the Addi Express, the loop size is set by two fixed things:

1. Needle pitch (spacing): ~6.5 mm center-to-center between needles.
2. Fixed hook/gate depth: determines how large each loop is pulled.

Because you can't dial a tension number the way you can on a flatbed knitting machine, the machine effectively "locks in" a loose, chunky-leaning gauge. That gauge lands in the 6–8 mm hand-needle zone rather than on one exact size.

Gauge Comparison (Worsted / Aran-ish weight)

✓ Math check: Addi gauge of ~3.5–4 sts/in falls squarely between 6 mm (4 sts/in) and 8 mm (3.25 sts/in), centering on 7 mm — consistent with the "7 mm closest" statement above.

Practical Substitution Guide for Beginners

If a hand-knit pattern calls for:

• 6 mm / US 10: Your Addi fabric will be very slightly looser. Use it as-is; just knit a test tube and measure.
• 7 mm / US 10.75: Near-perfect match — you can usually follow stitch counts closely.
• 8 mm / US 11: Your Addi fabric will be slightly tighter/denser. Fine for most projects.
• Below 5.5 mm / US 9 or smaller: The Addi will be too loose to match — the machine can't tighten up that far.

Best Yarn Choice

For worsted weight (also called medium / #4 / 10-ply), the Addi Express works best with:

• Smooth, plied worsted or light-Aran yarns.
• Avoid very thin (fingering/#1–2) yarns — they slip off the fixed hooks.
• Avoid bulky/#5–6 — they jam the needle gates.

Tip: If your worsted feels too thin and skips stitches, hold it doubled with a thin thread or use a light-Aran instead to fill the hook.

How to Confirm Your Own Equivalent (Recommended)

Because yarn brands vary, make a quick test tube:

1. Thread up your worsted and crank a plain tube for 20 rounds.
2. Remove it from the machine (crochet-hook bind-off or thread a tapestry needle through the live loops).
3. Lay it flat, relaxed (do not stretch).
4. Measure 4 in (10 cm) across and count stitches.
   • ~14–16 sts / 4 in → behaves like 7 mm.
   • ~16 sts / 4 in → behaves like 6 mm.
   • ~13 sts / 4 in → behaves like 8 mm.
5. Match that number to your pattern's gauge to decide whether to add or subtract stitches.

Quick Finishing Notes (Addi-specific)

• Bind-off: Thread a length of yarn through all live loops with a tapestry needle, pull snug, and secure — this is the machine equivalent of a hand cast-off.
• Blocking: Gently steam or wet-block the finished tube; the fabric relaxes and evens out, which also settles the final gauge (measure after blocking for accuracy).
• Row count: The Addi's built-in row counter (RC) counts rounds; use it exactly like a flatbed RC to track length.

Summary

Bottom line: Treat your Addi Express as roughly a 7 mm needle for worsted yarn, and always knit a small test tube to fine-tune before starting a real project.
