Sock length, converted
No-show, liner, low-cut, ankle, quarter, crew. Not one of them is defined anywhere. Each maker sets its own, and the product page usually gives you the word and no centimetres at all.
We never ask about your legs. We compare a sock you already own against theirs. Measure one pair that sits exactly where you like it, and read every chart against that.
The word ankle has been observed to span 5 to 12 centimetres measured from the top of the heel to the top of the cuff. One end just clears the ankle bone. The other end is halfway up the calf.
That is the whole difficulty. “Ankle” is not a length; it is a position relative to a body. And legs differ, so the same sock lands in a different place on two people. Faced with that, every maker settled on its own centimetres and stopped mentioning them.
Length naming has never been standardised. That is the state of the trade, not any brand’s fault, and we make no such allegation. Nobody was ever obliged to agree.
So we change the reference point. Not your leg, and not their vocabulary: a pair you already own and already like. Measure it once — top of the heel to the top of the cuff, laid flat — and every chart afterwards is arithmetic.
How it works
Lay it flat, unstretched, and run a tape from the top of the heel to the top of the cuff. Photograph it, or just type the figure. That one number is your benchmark, and it stays on the rule at the top of every page.
Sock on a table. Never on a foot, never on a leg.
Screenshot the size chart, or the block of measurements, and drop it in. We read the rows, work out whether the figures are centimetres or inches, and mask the maker's name before anything reaches the screen.
No chart at all, only a word? Say so — that is step 3's problem, and we handle it honestly.
Both lengths land on the same graduated axis: your brass slide, and their band beside it. Higher or lower, and by how much. If they never gave a measurement, you get a fog field and the span the word covers — not a number we made up.
Every reading prints as plain text, figures and all.
The reading
Your benchmark is a brass slide. Theirs is a band beside it on the same graduations. Higher or lower, and by how much — a distance you can see rather than a sentence you have to trust.
And when the chart gives nothing but the word, the second scale changes substance entirely. It becomes a fog field with no figure in it, because When a brand gives only the word, we do not turn it into a number. We show what that word spans across the market and tell you to ask them for the measurement.
Across the market, ankle has been seen to span 5–12 cm — one end just clears the ankle bone. the other end is halfway up the calf. We are not going to turn that into a figure for this pair, because we do not have one.
Ask them for the flat measurement from the top of the heel to the top of the cuff. One line in a message, and the guesswork is gone.
Free tier: the downloadable chart and naming-span card carry a watermark across the illustration. The wording above — including what we cannot know, and whether a measurement was given at all — is never covered by it.
Observed spans
Laid on the same graduations, the overlaps do the arguing. “Quarter” begins while “ankle” is still running. “Low-cut” and “ankle” share four centimetres between them. A pair described by either word could arrive at the same length — or eight centimetres apart.
Observed spans, measured from the top of the heel to the top of the cuff on a sock laid flat. They are what these words have been seen to cover, not what they mean — no definition exists to record. A pair from any one maker sits somewhere inside its band, and only that maker can say where.
Landing charts and naming-span cards, at the size they are read at. Abstract graduations throughout — no leg, no foot, no body, and no maker’s name.

Questions
The first two are the ones that decide whether this tool is worth anything. Both are answered against our own interest.
No. Not approximately, not with a wide margin, not at all.
What we can tell you is what the word has been seen to span across the market — for “ankle”, anywhere from 5 to 12 cm above the heel, which is the difference between just clearing the ankle bone and reaching halfway up the calf. That is a genuinely useful thing to know before you buy, and it is not the same thing as an answer.
The right next step is to ask them: “What is the flat measurement from the top of the heel to the top of the cuff?” Most sellers can answer in a line. Inventing a figure that looks settled would be far more likely to make you buy the wrong pair than admitting we do not have one.
The free tier keeps one benchmark and five conversions a month, for as long as you want it. No card, and nothing turns into a subscription on its own.
