One Swiss Knife in the exact shape of your life.

Knitter's Gauge

Knitter's Gauge, a small reckoner that computes in your browser and stores nothing. No account, no cloud, no telemetry.

Live · runs in your browser · no network

This is not a screenshot. It's the real tool, running right here: go on, put something in it.

Open the demo full-screen: /demos/knitters-gauge.html

Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.

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.

Standing facts

In ten years

Knitter's Gauge computes; it doesn't hoard. Open the file in 2036 and it will do the same arithmetic it does today, because the arithmetic is written into the file and nothing about it needs a server to agree.

If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.

Getting your data out

There is nothing locked in to get out: copy the numbers, or keep the file. Either way you owe no one a request form. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.

Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.

Who else sees this

Nobody. Knitter's Gauge works out its answer in your browser and forgets it the moment you close the tab: there is no store to breach, because nothing is stored. There is no account, no telemetry, no analytics, and no code in the file that opens a network connection, pull the cable and watch it carry on working. How privacy works across the Reckoners tools →

Questions people ask

01

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.

02

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.

03

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.
