Kiabi size guide

Official chart in centimetres: women, men, kids, and baby.

About this chart

Kiabi's lingerie chart also applies to the brands it sells: Bestform, DIM, Sans Complexe, Billet doux, Cache cœur, Playtex and Mojito. Charts specific to other brands on the same page (Adidas, Sans Complexe, DIM) are not included here, nor are women's tights, home linen and suit jackets, whose French size column contradicts itself (XL as 56/58, then 2XL as 50/52).

Women

Sizes 46 and 48 also appear in the plus-size chart, 1 cm apart on waist and hips (87 vs 88 cm waist in size 46). Both charts are shown as published.

Leg lengths

Inseam in cm by jeans cut: for the same L30 length, 71 cm in slim or mom, 83 cm in wide leg. Kiabi notes these lengths are approximate and depend on the rise of the trousers. No wide leg in L28.

Bras

Find the row for your underbust measurement, then the column where your bust measurement falls: the size to order is the row number followed by the cup letter. Example: 68 to 72 cm underbust and 86 to 88 cm bust give an 85C.

Sports bras

The sports bra sizes leave gaps: a bust of 85 to 87 cm, 93 to 95 cm or 101 to 103 cm falls into no size, and Kiabi does not say which to pick.

Briefs

In briefs, a 34 is an S, whereas in clothing a 34 is an XS. Above size 48, Kiabi lists two 50/52 rows: the one at 94–98 cm waist, smaller than size 48, is left out.

Tops and outerwear

For sizes 3XL to 7XL, Kiabi publishes waist measurements identical to those of sizes XXS to L (a 64 cm waist for a 3XL with a 128 cm chest), and does the same for the waist and hips of bottoms. These values, clearly copied by mistake, are left out: only the size conversion and, for tops, the chest measurement are given.

Underwear

Kiabi lists two rows for size 34 (66 then 70 cm waist) and two for size 36 (74 then 78 cm), grouped here as ranges. Sizes 54 and 56 appear in two charts with different values (114 cm waist in one, 118 in the other); the plus-size chart values are used. The hip measurement for 56 (138 cm) exceeds that of 58 (132 cm): probably a typo, value shown as published.

Kids

Girls

Two inconsistencies in the girls' chart, shown as published: the waist for age 12 (60 cm) is smaller than for age 10 (61 cm), and sizes S/age 16 and M/age 18 share the same height (165 to 170 cm).

Girls — plus fit

The plus fit keeps the height for the age but widens chest, waist and hips: at age 8, a 64 cm waist instead of 57.

Baby

New chart (items labelled "Nouveau taillant")

Kiabi has revised its baby sizes: clothes labelled "Nouveau taillant" (new sizing) follow this chart (except underwear, bodysuits and pyjamas), others follow the previous chart below. The new chart runs larger: 12 months now means 80 cm height, against 73 to 76 cm before. Size 00M is the smallest, for 44 cm.
