What Size Press-On Nails Do I Need? (UK Sizing Guide 2026)
Quick answer: Most press-on brands use a 10-point size scale (0–9). Bling Art sets go two steps further — 24 nails across 12 sizes (0–9 plus half sizes 5.5 and 6.5), two of every size — so the awkward in-between nail beds are covered too. To find your size: measure across the widest part of each natural nail in millimetres, then match to the chart below.
The Bling Art press-on nail size scale
Sizes run from 0, the largest (14mm across the cuticle), down to 9, the smallest (6.7mm). Most brands stop at the ten whole numbers. Bling Art adds two half sizes in the middle of the range — 5.5 and 6.5 — which is why our sets contain 12 sizes rather than 10.
| Size | Width (mm) | Typical fit |
|---|---|---|
| XXL (0) | 14 mm | Thumb (largest) |
| XL (1) | 13 mm | Thumb |
| XL (2) | 12 mm | Thumb / index finger |
| L (3) | 10 mm | Index finger |
| L (4) | 10 mm | Index / middle finger |
| M (5) | 9 mm | Middle finger |
| M (5.5) | 9 mm | Half size — middle / ring |
| M (6) | 9 mm | Ring finger |
| S (6.5) | 8 mm | Half size — ring finger |
| S (7) | 8 mm | Ring / little finger |
| XS (8) | 7 mm | Little finger |
| XS (9) | 6.7 mm | Little finger (smallest) |
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 the size for each of your ten fingers
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 0 (14mm) or Size 1 (13mm)
- Index finger: Size 2 (12mm) or Size 3 (10mm)
- Middle finger: Size 4 (10mm) or Size 5 (9mm)
- Ring finger: Size 6 (9mm) or Size 6.5 (8mm)
- Little finger: Size 8 (7mm) or Size 9 (6.7mm)
This isn't universal — some women have wider or narrower nail beds. Always measure.
What if I'm between two sizes?
Check the half sizes first — 5.5 and 6.5 exist precisely for this. If you are still between two sizes, go smaller, never larger. A slightly smaller press-on sits inside the nail bed and can be blended in; a larger one overhangs, catches on clothing and lifts early.
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, take the next size larger (the lower number) and file the inner edges down 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 the smallest sizes 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 — sizes 0–9 plus half sizes 5.5 and 6.5, two nails of every size, 24 nails per set. Most brands supply 10 sizes or fewer, which is why in-between 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.
