Compare two size charts that disagree, measurement by measurement
Size labels travel badly between markets. Measurements do not. This compares numbers instead of letters.
Two charts, pasted as text
One row per size, tab-separated, with the measurement names on the first line. Use the same name on both sides — chest in one chart and bust in the other will not be compared.
Closest match: L
Label L is the only size where both charts agree within 2 cm.
| Size | Measurement | Chart A | Chart B | Difference |
|---|---|---|---|---|
| M | chest | 104 | 100 | -4 off |
| M | length | 70 | 68 | -2 within |
| M | shoulder | 46 | 45 | -1 within |
| L | chest | 108 | 106 | -2 within |
| L | length | 72 | 71 | -1 within |
| L | shoulder | 48 | 47 | -1 within |
| XL | chest | 112 | 112 | 0 within |
| XL | length | 74 | 73 | -1 within |
| XL | shoulder | 50 | 49 | -1 within |
This compares what you typed. If one chart is a body measurement and the other is a garment measured flat, the gap is in the inputs, not in the arithmetic — which is the single most common reason two charts appear to disagree.

It compares what you type. If one chart measures a garment flat and the other measures a body, the difference is in your inputs, not in the maths.
Where the inputs come from. Both charts, using the same measurement name on each side, and the tolerance you are willing to accept.
