Knitting pattern calculator: a pattern for your measurements and your yarn
Lively Loop does the stitch maths for you. Enter your measurements and swatch gauge, and the builder writes a complete pattern — from cast-on to finishing — with explanations and row-by-row tables.
What you can make
- Set-in sleeve sweater with a shaped cap

- V-neck vest, cardigans with button bands
- Socks, top-down or toe-up

- Lace scarves and cowls
- Cables as a panel or allover, and your own colourwork

How it works
- Knit a swatch about 15×15 cm (6×6 in) in your yarn, wash and dry it, and count stitches and rows over 10 cm.
- Enter your measurements or start from a standard women’s, men’s or children’s size.
- Choose the construction: fit, neckline, collar, shoulder slope, waist shaping, cables or colourwork.
- Get your pattern: every section explains what you are doing and why, links to illustrated techniques and lists every row. Row counter, knitting mode and PDF printing included.
Why you can trust the numbers
The builder checks that stitch counts carry over between sections, that the sleeve cap matches the armhole, that the increases fit into the sleeve length and that the 2×2 ribbing is symmetric. If something doesn’t add up, you see a warning before you cast on.
FAQ
Is it suitable for beginners?
Yes. Every section explains what you are doing and why, and every technique has a “How” button with pictures and steps. Row-by-row tables and the row counter keep you on track.
Which abbreviations does it use?
Standard US pattern abbreviations: k, p, k2tog, ssk, M1L, M1R, sl1, RS/WS, pm/sm, and cable notation such as 2/2 RC. See the abbreviation list.
My yarn is different from the pattern yarn. What now?
The pattern is calculated from your own gauge, so knit a swatch with the yarn and needles you will use and the numbers will fit it.
How much does it cost?
The first 7 days are free, then it is a monthly subscription.
