What Size Press-On Nails Do I Need? (UK Sizing Guide 2026)
Quick answer: Most press-on brands use a 10-point size scale from XS to XXL. Bling Art sets go two steps further — 24 nails across 12 sizes (XS–XXL), two of every size — so narrow and wide nail beds are both covered. To find your size: measure across the widest part of each natural nail in millimetres, then match to the chart below.
The standard press-on nail size scale
This is the 10-point scale most brands use. Bling Art adds two further sizes at the extremes, which is why our sets contain 12 rather than 10.
| Size | Width (mm) | Typical fit |
|---|---|---|
| XS (0) | 7 mm | Little finger (some adults) |
| S (1) | 8 mm | Little finger / ring finger |
| S (2) | 9 mm | Ring finger |
| M (3) | 10 mm | Ring / middle |
| M (4) | 11 mm | Middle finger |
| L (5) | 12 mm | Index finger |
| L (6) | 13 mm | Index / thumb |
| XL (7) | 14 mm | Thumb |
| XL (8) | 15 mm | Thumb (larger) |
| XXL (9) | 16 mm | Thumb (largest) |
For the exact per-shape charts, see our nail size guides — there are separate ones for squoval, almond, oval and ballerina.
How to measure your nail size
- Find a millimetre ruler (most stationery rulers have a mm side)
- Place each natural nail flat against the ruler
- Measure across the widest point of your nail (cuticle area, not tip)
- Round to the nearest millimetre
- Match the measurement to the size chart above
- Write down all 10 sizes (one per finger)
Typical UK adult women's sizing pattern
Most UK adult women find their fingers fall in these sizes (left hand and right hand are usually similar):
- Thumb: Size 7 (14mm) or Size 8 (15mm)
- Index finger: Size 5 (12mm) or Size 6 (13mm)
- Middle finger: Size 3 (10mm) or Size 4 (11mm)
- Ring finger: Size 2 (9mm) or Size 3 (10mm)
- Little finger: Size 1 (8mm) or Size 2 (9mm)
This isn't universal — some women have wider or narrower nail beds. Always measure.
What if I'm between two sizes?
Always size down. A slightly smaller press-on nail can be perfectly applied and looks fine. A slightly larger one will catch on bedding/clothing and pop off. You can also file the sides of a slightly oversized nail to fit.
What if a size is missing?
Bling Art sets include 24 nails across 12 sizes — two of every size, so a full manicure never runs you short. If you have used both of one size, file down the next size up to fit. Press-on nails file easily with the included nail file.
Press-on nail sizing for teenagers and children
Most UK teenagers (13+) wear adult sizes. Younger children typically need XS or specialist children's press-on sets. Always measure rather than assuming.
Shape matters as much as size
Once you know your millimetre sizes, the other half of the fit question is shape. A squoval and a coffin in the same size sit very differently on the same nail bed. The cheapest way to find yours is to try several at once rather than guessing.

FAQs
How many sizes are in a Bling Art set? 12 — XS through XXL, two nails of every size, 24 nails per set. Most brands supply 10 sizes or fewer, which is why narrow and very wide nail beds often struggle to find a fit elsewhere.
How much are 5 sets? £9.99 — £2 a set, 120 nails, free UK delivery. The multi-set discount applies automatically once five sets are in your basket. Two sets are £5.99 and three are £8.
Do all shapes use the same size chart? Yes. The millimetre widths above apply across squoval, oval, almond and coffin. Only the tip length and profile change.
What if my two hands are different sizes? Common, and not a problem — each set has two of every size, so you can size each hand independently.
