Jeans Size Calculator

Wrap a soft tape measure around your waist at the level of your belly button — this is typically the narrowest part of your torso. Keep the tape snug but not tight, and stand straight. That number (in inches or cm) is your waist measurement for jeans sizing.

Stand straight and measure from your crotch (the top of the inner thigh) straight down to your ankle bone. Alternatively, lay a pair of jeans flat and measure from the crotch seam to the bottom hem along the inside leg. This gives your inseam length.

In women's US sizing, a waist size of 32 inches typically corresponds to a US size 14/15, UK size 18, and EU size 44. This will vary slightly by brand, so always check the specific brand's size chart when possible.

US jeans sizes are usually shown as two numbers — waist × inseam — both in inches. So '32×30' means a 32-inch waist and a 30-inch inseam. Women's jeans sometimes drop the inseam and use just the waist number (e.g. '28') or a general size (XS–XL).

A UK women's size 10 corresponds to approximately a US size 6, which typically equates to a 28-inch waist jeans size. Keep in mind that UK and US sizing systems differ by about 4 sizes.

European (EU) jeans sizes for women are typically about 30 more than the US size — so US 28 ≈ EU 38. For men, EU sizes are often equivalent to the waist in centimetres divided by 2.54 and rounded. Always double-check with a brand's conversion chart.

It depends on the fabric and fit style. Denim with low or no stretch tends to give slightly, so sizing up is usually safer. For stretch or jeggings, you can often size down. When in doubt, try both sizes and choose the one that fits best at the waist without gaping.

Yes, most 100% cotton denim can shrink by 3–7% after the first wash, especially in hot water. Pre-washed or sanforized denim shrinks less. If your size is borderline, consider sizing up to account for potential shrinkage, and always wash in cold water to minimise it.
