About this app

Knitting gauge calculator: turn your measured swatch and target length into stitch or row counts you can check. Knitting Gauge & Pattern Math keeps your source numbers, arithmetic and rounding visible, so you can check each result against your own swatch.

GAUGE AND ROW COUNTS

Enter your measured stitch or row count, measured length and target length. Calculate a target count in centimetres or inches. See the raw answer, rounded count and rounding change. Resize an existing count using an explicit source and target length.

STITCH CHANGES

Distribute single-stitch increases or decreases across flat or circular work. Choose protected edge stitches and inspect balanced gaps and original-stitch positions. Schedule changes across an explicit row span.

BUTTONHOLE SPACING

Set your stitch span, first position, ending margin, opening width and number of buttonholes. Review start positions and clearance assumptions. Zero-width mode is a point-placement helper.

USEFUL FREE CALCULATIONS

Use all core calculators, save one project with the latest calculation of each type, label an optional manual final count without changing the raw answer, choose centimetres or inches, and use light, dark or system appearance. Export and import local projects as JSON recovery backups.

OPTIONAL LIFETIME PRO

Keep additional projects and calculation history, name and reuse gauge swatches, and use a project row counter with undo. Choose additional rounding rules. Save or share project math as CSV or a text sheet. Pro is a one-time purchase, not a subscription.

YOUR OWN MEASUREMENTS

Calculations and saved projects work locally. There is no account, cloud-sync service or pattern collection. File export/import use Android's document picker. Google Play processes purchases and automatic billing-service technical data; see the privacy policy.

This is an arithmetic helper for your own inputs. It does not provide proprietary patterns, finished-garment predictions or guaranteed fit. Check your measured swatch, units and assumptions before using a result.

For knitters considering Mnemosina knitting patterns, this knitting calculator offers a separate worksheet for buttonhole placement on a cardigan band. Enter the usable span and edge clearance from your own design, then review the positions before marking the fabric.
