Size charts
Your fit, in one place — and the numbers every pack is built from.
Brand → Size charts in the header. Three fit blocks — Women's, Men's, Unisex — and a chart for each garment category. The menu says how many rows you have set, because a chart nobody has touched is a pack measured against an apparel-industry standard rather than against your block.
They are blocks, not genders. A block is the set of proportions a garment was cut to, and a woman wearing a men's-block oxford is wearing a men's-block oxford. That is what a factory cuts, so that is what the pack says.
One column, not a grid
You enter the measurement at your base size and how much it grows per size; every other size is computed from those two. Click a computed size to set it by hand instead — real grading is rarely linear at the extremes, and a hand-set size is outlined so you can see which ones you fixed.
Inches or centimetres. The toggle changes what is shown and never what is stored, so switching back and forth cannot walk a number.
Beneath the table is a drawing of the garment with each measurement numbered on it, so chest width is a line on a picture rather than a phrase you have to picture yourself.
These are starting points, not your measurements
A chart arrives prefilled with apparel-standard values so the screen is useful the first time you open it. They are not your brand's numbers — they are what a garment of that kind typically measures.
Why they cannot simply be correct out of the box: the depth a spec block needs is not published anywhere. Body measurement standards are paywalled, and they are body measurements — a finished garment is a body plus ease, and ease is a brand's own decision. Manufacturer specification sheets are public and exact and two to four rows deep, because the rest of a block is the thing a brand does not give away.
So the prefill has to pick an ease, and it picks one: every number arrives at a regular fit — skimming the body with ordinary ease, neither close nor loose. It says so beside the title, and the tooltip there names the other three, because on its own regular reads as "normal", which is not a measurement.
This matters more than it sounds. The same chest describes a fitted tee and an oversized one at two quite different numbers, so if you cut fitted, relaxed or oversized, those rows want editing rather than trusting. And not by one amount everywhere: an oversized tee adds room through the chest, the body and the sleeve, and adds nothing at all to its collar or its cuff. Trims are trims at any fit.
What editing one does
Anything you change is marked edited, and an edited row is used when a pack is generated — given as a figure to work from, with your grading step, so the pack comes back measuring your garment rather than a typical one. The pack then states it as specified rather than assumed, which is the difference between a factory being told a measurement and being handed a guess.
Rows you have not touched are deliberately not used that way. A prefilled default is not something your brand has said, and passing one off as your block would teach the pack to repeat a guess as though it were a decision.
Which is why one pass through this screen is worth more than correcting packs one at a time afterwards. A measurement fixed here is fixed for every pack you make from then on.
What a chart does not decide
A chart holds the block — what an M is for your brand. It does not hold what a particular style does differently, and it does not try to. A cropped version of your own tee is still cut to your block; its length is a decision about that style, and it belongs in that pack.
