Store body measurements for agent sizing

The chart changes. Your body does not.

Every seller writes a different chart. Some list chest and length. Some list hip only, under the heading 臀围. Some list nothing at all and put the numbers in an album note.

You cannot fix that. You can stop re-deciding. Save your measurements once, and every chart you meet reads against the same eight numbers.

The eight fields Credenza uses

Open Profile, then Your sizes.

• Height and weight — these two alone let Credenza estimate the rest.
• Chest — around the fullest part, tape level under the arms.
• Shoulder — seam to seam across the back.
• Arm length — shoulder seam to wrist bone, arm relaxed.
• Waist — where you wear your trousers, not the narrowest point.
• Hip — around the fullest part. This is the 臀围 row on a Chinese chart.
• Inseam — crotch to floor, no shoes.

How to take them

• Use a soft tape. A metal one gives a number, not a measurement.
• Measure over a t-shirt, never over a coat.
• Keep the tape level and snug. Do not pull it tight.
• Stand relaxed. Do not hold your breath or flex.
• Measure twice. If the two differ, take the larger one.

No tape? Enter height and weight only. Credenza estimates chest, waist, and hip from those two, and marks the result with a question mark so you know it is a guess, not a measurement. A measured field always wins over an estimate, so you can fill the rest in later without losing anything.

Inches or centimeters, your choice

Type in the unit you think in. Credenza stores centimeters under the hood, because that is what sellers publish.

When you flip the unit toggle, every value you already typed converts with it. 38 in becomes 96.5 cm. A number is never silently reinterpreted as the other unit.

Usual sizes, for the charts that do not exist

Fill in the size you usually buy for tops, bottoms, and shoes — plain text, like M, 32, or US 10.

A card with no seller chart shows one of these, labelled YOUR USUAL. The label is deliberate. It tells you the number came from your habit, not from a chart, so you do not mistake a default for a decision.

Fit preferences move the pick

Open Profile, then Fit preferences. Each category you own gets two rows.

• Length — cropped, regular, or long. Shorts use short, mid, and long.
• Looseness — slim, regular, or baggy. Shirts and outerwear use oversized in place of baggy.

Looseness moves the letter one step. Slim sizes down. Baggy or oversized sizes up. Regular changes nothing. The reason line on the card names the preference that moved it, so the suggestion is never a silent magic number.

Four labels, four different meanings

• SIZE — you typed it in Edit. It always wins.
• AI SIZE — read from the seller chart against your measurements.
• AI SIZE with a question mark — same, but part of your profile was estimated from height and weight.
• YOUR USUAL — no chart on this item, so the card falls back to your habit.

On your device, and nowhere else

Body measurements stay on the device. They are not part of the synced shelf, they are not in a shared link, and no server function receives them. Turning sync on does not change this.

Export the whole shelf as JSON at any time from Profile → Import & backup. Erase every device record from Profile → Erase my data. The privacy notice lists each store and how to delete it.

A profile is not a tailor

Credenza reads the chart the seller published. If that chart is wrong, the suggestion inherits the error. Measurements also do not know how a fabric behaves — a rigid canvas and a stretch knit at the same chest number wear differently.

A saved profile removes the avoidable mistakes: the guess, the unit mix-up, and the chart you never opened. It does not remove fit risk.
