Knitter's Gauge
Reckonersweight 1reckoner · computes, doesn't store
The pattern says 22 stitches per 10 centimetres; your swatch, knitted with love and your actual hands, says otherwise. Knitter's Gauge does the conversion arithmetic between the pattern's tension and yours, so the jumper comes out jumper-sized instead of tent-sized. It computes the adjustment and stores nothing — the swatch has suffered enough without a database.
This is not a screenshot. It's the real tool, running right here — go on, put something in it.

Questions people ask
What do I do when my knitting gauge doesn't match the pattern?
Measure your swatch, give the tool your numbers and the pattern's, and it computes the adjustment. The maths that usually happens on the back of the pattern in pencil happens in the page instead.
Does this knitting calculator work offline at my knitting group?
Yes — it is a single HTML file that runs in your browser with no connection, computes on the spot, and stores nothing. Village hall, train, sofa: wherever the knitting happens, it works.
Do I really need to knit a gauge swatch first?
The calculator needs your real numbers to work from, and the only place they come from is a swatch. Yes, everyone hates knitting them. Yes, it is still faster than reknitting a cardigan.
