Lululemon Size Chart and Fit Guide

Lululemon sizing is easiest when you ignore the letter on the tag and match your body measurements to the current official women's size guide or men's size guide. Many women's bottoms use numeric sizes, many women's tops and bras translate those numbers into alpha sizes, and most men's apparel is shown in both waist or alpha formats.

How lululemon sizing works

The current guides show three important patterns. First, women's bottoms run from numeric size 0 to 20. Second, women's tops map numeric sizes 0 to 22 into alpha sizes from XXXS to 2X, while bras use band size plus under-bust measurement. Third, men's bottoms run from waist size 26 to 50, while men's tops run from XS to 5XL in the women's guide and the men's guide.

Women's bottoms size chart

Use waist and hip first. The table below is taken from lululemon's current women's bottoms chart here.

Numeric size	Waist	Hip
0	21.5 in	31.5 in

12	33 in	43 in
14	35 in	45 in
16	39 in	47 in
18	41 in	49 in

Women's tops and bras

For tops, chest measurement is the fastest filter. For bras, lululemon uses band size, numeric size, and under-bust measurement together in the same guide.

Women's tops	Numeric size	Chest
XXXS	0	28.5 in
XXS	2	30 in
XS	4	31 to 32 in
S	6	33 to 34 in
M	8	35 to 36 in
L	10	37 to 38.5 in
XL	12 to 14	40 to 42 in
1X	16 to 18	45 to 47 in
2X	20 to 22	49 to 51 in

Bra band	Numeric size	Under bust
28	2	24 7/8 in
28/30	4	26 in
30/32	6	27 3/4 in
32/34	8	29 1/4 in
34/36	10	30 in
36/38	12	32 3/4 in
38/40	14	35 in
40/42	16	37 1/8 in

Men's bottoms size chart

This grouped version is derived from lululemon's current men's bottoms chart to keep the table readable from the official guide.

Alpha size	Waist sizes	Body waist	Hip
XXS	26	27 in	33.5 in
XS	27 to 28	28 to 29 in	34.5 to 35.5 in
S	29 to 30	30 to 31 in	36.5 to 37.5 in
M	31 to 32	32 to 33 in	38.5 to 39.5 in
L	33 to 34	34 to 35 in	40.5 to 41.5 in
XL	35 to 37	36 to 38 in	42.5 to 44.5 in
XXL	38 to 40	39 to 41 in	45.5 to 47.5 in
3XL	42 to 44	46 to 48 in	48 to 50 in
4XL	46	50 in	52 in
5XL	48 to 50	52 to 54 in	54 to 56 in

Men's tops size chart

Lululemon's men's tops chart is straightforward and uses chest measurement as the main input in the official guide.

Alpha size	Chest
XS	35 to 36 in
S	37 to 38 in
M	39 to 40 in
L	41 to 42 in
XL	43 to 45 in
XXL	46 to 48 in
3XL	50 to 52 in
4XL	53 to 55 in
5XL	56 to 58 in

How to measure correctly

Waist: measure the smallest part of your waist.
Hip: measure the widest part of your hips and seat.
Chest: measure around the fullest part with the tape flat.
Under bust: measure around the ribcage just below the bust.

Those are the same measurement points lululemon uses in its current guides for women and for men.

What to do if you are between sizes

The official women's guide adds two useful caveats on the current page: Contour Fit leggings and shorts measure smaller at the waist and larger in the hips, and shelf bra tops measure smaller because of the built-in band. In practice, size for the measurement that matters most for the item: waist and hip for leggings, chest for tops, and under-bust for bras. If one measurement sits on the line, the product's intended feel decides the tie-breaker: closer for compression, looser for casual wear.

Bottom line

Start with the official chart, not your usual mall size. For lululemon, the best match usually comes from waist and hip for bottoms, chest for tops, and under-bust for bras. Once those numbers line up with the current guide, you are far less likely to miss on fit.
