Topshop sizing is easiest to shop as UK sizing first. On current ASOS product pages, Topshop items repeatedly show conversions such as UK 8 = EU 36 = US 4, while some denim listings also use waist-and-length notation like W26 L32 here and here. Start with the live ASOS size guides, then confirm the item page because ASOS says some brands may vary from the standard measurements.

How Topshop sizing works now
Topshop currently sells through ASOS, and current Topshop product pages describe the range as available on ASOS in edits such as petite, maternity, tall, and curve example. In practice, that means the safest path is: use ASOS's published body-measurement charts as your starting point, then use the product page's own size guide and fit notes for the exact item you want.
Topshop clothing conversion chart
The current ASOS women's size guide is a body-measurement guide, not a garment-measurement guide here. For the standard numeric size run, the official conversions are:
| UK | US | EU | IT |
|---|---|---|---|
| 4 | 0 | 32 | 36 |
| 6 | 2 | 34 | 38 |
| 8 | 4 | 36 | 40 |
| 10 | 6 | 38 | 42 |
| 12 | 8 | 40 | 44 |
| 14 | 10 | 42 | 46 |
| 16 | 12 | 44 | 48 |
| 18 | 14 | 46 | 50 |
Tops and dresses body measurements
ASOS's current dresses guide gives the clearest Topshop-compatible body-measurement table for standard women's numeric sizing here. Use these as body measurements, not finished garment dimensions:
| UK | Bust | Waist | Hips |
|---|---|---|---|
| 4 | 31 in / 78 cm | 24 in / 60 cm | 33 in / 83.5 cm |
| 6 | 32 in / 80.5 cm | 25 in / 62.5 cm | 34 in / 86 cm |
| 8 | 33 in / 83 cm | 26 in / 65 cm | 35 in / 88.5 cm |
| 10 | 35 in / 88 cm | 28 in / 70 cm | 37 in / 93.5 cm |
| 12 | 37 in / 93 cm | 30 in / 75 cm | 39 in / 98.5 cm |
| 14 | 39 in / 98 cm | 31 in / 80 cm | 41 in / 103.5 cm |
| 16 | 41 in / 103 cm | 33 in / 85 cm | 43 in / 108.5 cm |
| 18 | 44 in / 110.5 cm | 36 in / 92.5 cm | 46 in / 116 cm |
Actual dress length still changes by style, and ASOS says to check each product page for item-specific length details.
Jeans and trousers sizing
For standard numeric bottoms, the current ASOS women's jeans and trousers guide uses the same conversion ladder below here:
| UK | US | EU | IT |
|---|---|---|---|
| 4 | 0 | 32 | 36 |
| 6 | 2 | 34 | 38 |
| 8 | 4 | 36 | 40 |
| 10 | 6 | 38 | 42 |
| 12 | 8 | 40 | 44 |
| 14 | 10 | 42 | 46 |
| 16 | 12 | 44 | 48 |
| 18 | 14 | 46 | 50 |
Topshop denim also appears on live product pages with W/L sizing. Current examples show models in UK 8 / W26 L32 on straight-leg and mom styles straight leg. If a listing is sold in W/L, do not force it back into a UK number without checking that product's own size guide first.
Topshop denim fits explained
The current Topshop denim fit guide describes the core fits this way:
| Fit | What ASOS says |
|---|---|
| Straight Classic | Mid-rise, straight leg, comfort-stretch denim |
| Jamie Flare | High waist, flared leg, super-stretch denim |
| Mom | High waist, tapered leg, rigid denim |
| Joni Flare | Power-stretch denim |
| Editor | High waist, straight leg, rigid denim |
| Dad | Mid-rise, loose leg, rigid denim |
| Relaxed Flare | High waist, flared leg, comfort-stretch denim |
This matters because rigid and stretch denims will not fit the same even when the nominal size is identical.
Topshop shoe size chart
ASOS's current women's footwear chart is the closest official guide available when shopping current Topshop shoes on ASOS here:
| UK | EU | US | Foot length |
|---|---|---|---|
| 2 | 35 | 4 | 212 mm |
| 3 | 36 | 5 | 220 mm |
| 4 | 37 | 6 | 229 mm |
| 5 | 38 | 7 | 237 mm |
| 6 | 39 | 8 | 246 mm |
| 7 | 40 | 9 | 254 mm |
| 8 | 41 | 10 | 262 mm |
| 9 | 42 | 11 | 270 mm |
ASOS also says that if your foot measurement falls halfway between sizes, select the larger size.
How to measure for Topshop
ASOS's current measurement guide says to measure across the fullest part of the bust, around the natural waistline, at the widest part of the hips, and from the top of the inside leg at the crotch to the ankle bone for inseam here and here. For shoes, measure foot length on a level floor with your heel against a straight edge here.
Fit notes before you order
Do not assume one Topshop item predicts the next. Current item pages show why: a straight-leg jean says to select your usual size here, a wrap mini dress is marked true to size here, and a textured wrap top is simply listed as a regular fit here. The safe rule is to treat the chart as a starting point, then adjust for cut, fabric, stretch, and whether the listing is standard, petite, tall, maternity, or curve.
Bottom line
Use UK sizing as your anchor, convert with the current ASOS tables, and treat W/L denim sizing as its own system when the listing uses it. The charts above are useful current guides, but the item page still decides the final fit because Topshop styles on ASOS do not all use the same fabric, rise, stretch, or silhouette.
