Start with a pair you already wear
Lay your best-fitting jeans flat. Measure the waistband across the top and double it. Measure the inseam from the crotch seam to the hem. Measure the front rise from the crotch seam to the top of the waistband. Write the three numbers down.
Those numbers are your size. The tag inside the jeans is a label someone else chose.
Mapping measurements onto a listing
Most listings publish a flat waist and a length. Fewer publish rise. If rise is missing, ask — it is the difference between jeans that sit on the hip and jeans that sit under the ribs.
Compare flat waist to your measured flat waist, not to your body. A 42 cm flat waist is an 84 cm circumference; if you measure 84 cm around your waist, that pair will be snug, not comfortable.
Rigid vs stretch
Rigid denim relaxes about 2 cm at the waist over a week of wear and does not shrink back fully. Stretch denim fits from day one and sags at the knee by month three. If you are between sizes: rigid, size up; stretch, stay true.
The three failure modes
Waist gap. A pair that fits the hips but gaps at the back needs a belt, not a smaller size.
Stacking. Inseam longer than your leg creates stacks at the ankle. Some people want this; most do not.
Shrinkage. Cotton denim can lose 2–4 cm in the waist after a hot wash. Wash cold for the first three cycles.

Quick answers
Should I trust the size tag or the measurements?
Measurements. Tags vary by factory, and vanity sizing is common.
How much does denim shrink?
Plan for 2–4 cm in the waist and 1–2 cm in length after a hot wash; cold washing limits it to about half.
