oh my measure
One pass with a tape and your size is ready. Eight scales, letter S/M/L among them.
2 Waist
Between the ribs and the hips that line is easy to lose. Bend to one side and the crease falls right along it.
Don’t hold your stomach in: the tape settles below the real line, and your bottoms size slides down with it.
Waist 63.1 cm
3 Leg length
Leg length is taken two ways: down the outside seam from the waist, and down the inseam from the crotch. Both are marked “needs a helper” — holding a tape in mid-air all the way to the floor is not a one-person job.
You can skip the inseam — the app derives it from the outside seam and the rise.
Outside seam 110.9 cm
4 Foot
Foot length decides the shoe size on its own. Everything else is width: the girth across the ball, over the bones that stick out furthest. At one and the same length, lasts come in different widths, and what pinches is usually the width.
Ball girth 21.7 cm
Stand on a sheet of paper and trace your foot with the pencil held upright — reading it against a ruler by eye comes out short. Take the ball girth standing, full weight on the foot, no tension on the tape. Measure both feet: buy for the larger one.
Foot length 24.1 cm
5 Height
The waist-to-height ratio and the body mass index in the summary above are both built on it. And the charts have a second job: the length grade — how long the garment is at the same size.
Stand barefoot against a wall, heels together, looking straight ahead. Tipping your head a couple of degrees moves the result more than you would think.
Height 172.9 cm
6 Bust
The bust measurement decides tops and dresses. A bra needs more than one number: the size is built from the difference between the bust and the underbust, which is why we ask for both.
Keep the tape horizontal and check the back in a mirror: if it has ridden up, the measurement comes out smaller than it is.
Bust 87.8 cm
Shoes
Shoe size is worked out from foot length alone. The scales differ not in the body but in what they print on the sole: some print the length of the last, some the length of the foot, and in different units.
Width
Length decides the number on the box. Width decides whether it pinches. It is worked out from the ball girth, not from the width of the foot: width is a line straight across, girth is the distance all the way around.
W = 0.25 × ball girth − 0.15 × foot length − a constant (17 for women, 16 for men). We use the women’s constant — this is the foot of the same figure standing on the stage above.
This is retail practice, not a chart of lasts: its step is 4 mm of girth, where the Russian standard 3927-88 steps 6 mm and the athletic Russian standard 24382-80 steps 8. That is why the width is marked approximate.
Letter widths — European F, G, H and American A through EEE — the app doesn’t state and won’t. The letter comes from a specific manufacturer’s own last tables, and no international system for width letters exists: ISO tried to define one (ISO/TR 3836) and withdrew the standard, because foot-size distribution varies too much from country to country.
Foot 24.0 cm
Last 25.0 cm 10 mm allowance
The dashed outline is the last: longer than the foot by the allowance. The European and British scales print its length; the Japanese one prints the foot itself.
Width from ball girth
Ball girth 23.6 cm
Width 6 · medium approximately
This value sits in the middle of its step — the widths on either side are further off.
This value sits right on the boundary: width 5 next door is just as likely.
The fifth step is disputed: some sources count it as narrow, others as medium.
The five numbers above have not moved once: not one of these scales prints width. Where it is printed at all, it is printed as a number of its own.
The conversion runs on the definitions of the units, not on any one brand’s chart: the English scales disagree by up to half a size, and men’s and women’s are not separated yet. This is a guide, not a guarantee of fit.
A bra size is the difference between two measurements. Whether it fits is decided by shape, and no measurement describes that.
Shape doesn’t change your size — it changes which style to look for. This is fitting-room practice, not a standard.
Two views: the width of the root reads from the front, fullness and projection from the side.
Sister sizes are right alongside: if a 75C is tight around the band, an 80B holds the same volume.
One set of measurements, and this is what comes out of it. Switch the system: four of the eight are here.
Where you sit inside a size
A size is a band of measurements, not one number. If you are near the edge, the size next to it is worth trying too.
Demo profile: bust 87.8 cm, waist 63.1 cm, hips 89.2 cm, foot length 24.1 cm, height 172.9 cm. Your own numbers give you your own row in this same table.
Quick path
Pick an item — we’ll ask only for the measurements it needs, one at a time. A T-shirt needs just one. Getting a size needs no account.
What you enter carries over between items: a dress will reuse the bust measurement from a T-shirt automatically. You can view and clear everything you’ve entered in the app.
Catalog
29 measurements from ISO 8559-1, from neck girth to foot length. Nine are enough for a size; the rest are for clothes made to measure.
11 measurements of the 29 can’t be taken on your own — the tape has to be held in mid-air. The app flags that before you pick the tape up.
Brands
An S at one brand and an S at another are different centimeters. So we don’t average: for these brands the app reads the chart they published themselves.
Profiles
Name a set of measurements and it stays. Next time the app fills it in for you: you open a garment and see your size straight away instead of starting with the tape again.
There is no save button. Once a set has a name, every later edit goes into it on its own — there is nothing to forget to press.
Yours, your family's, yourself a year ago. The cards sit in one grid, and the same measurement lines up in the same column across all of them.
Children's bodies are kept separately and do not clutter yours. Moving between the two screens resets neither.
Each card carries its name, how many measurements of the total are filled in, and when it was last updated.
Any body can be renamed, deleted with a confirmation, and sent as a link straight from its card.
For now a profile lives in the browser you created it in. If the browser refuses to store it, the app says so plainly rather than pretending it saved.
We don’t average, and we don’t round in silence.
Every result names the measurements it was calculated from, and the ones still missing for that category.
Next to your size are the ones on either side, with a mark for where your measurement falls. You see not only “you are a 40”, but that you are at the top edge of the 40s.
Every field says where to hold the tape and which points to look for. What you can’t take on your own is marked before you start.
One set of measurements in EU, US, UK, FR, IT, JP, RU and letter S/M/L at once — with a note on where that is a standard and where it is retail convention.
There is one chart, and there are many stores.
We hold the charts of 130+ brands and size against the one the brand published itself. One set of measurements, and your size at every one of them.
A row reading “94–98” covers 94 and 98 alike. We show which edge your measurement sits at, and name the size next door when you are on the boundary.
You take your measurements once. After that it is tops, bottoms, dresses, bras, shoes and rings in seven systems, with no converting by hand.
A governing standard does not exist everywhere. Europe has EN 13402, stepping 4 cm at a time; Russia has Russian standards 31396 and 31399; the US and the UK have no national clothing standard at all — since 1983 what they have is the voluntary charts of individual retailers. Hence “UK 18”, which five major chains print against a bust of anywhere from 104 to 113 cm.
Every scale, as tables, with sourcesA centimeter off at the bust or the hips moves the answer a whole size, so technique matters more here than the tape does. Hold it horizontal and without tension, and check where it sits at the back in a mirror. Measure the hips over the fullest part of the seat: that is the measurement people most often take too small on themselves.
