Salon-perfect soft-gel nails, sized in millimetres

How the sizing flow works
Three small steps, about two minutes, right from your phone.
Photograph with a reference
Place a credit card or coin beside your hand and take one photo. The known size calibrates the millimetre scale.
Align the measurement overlays
Drag a width handle onto each nail. NailFit converts pixels to millimetres from your calibration.
Fine-tune and save
Correct any nail to 0.1 mm and keep a printable report with every width in millimetres.
Built for fit-first nails
Whether you are ordering your first press-on set or running a full studio book.
Camera sizing with calibration
A credit card (85.6 mm) or coin (24.26 mm) anchors the scale, so estimates stay honest.
Manual correction, always
Every measurement is editable. You have the final word before any size is used.
Shareable sizing links
Professionals send a personal link; clients size themselves and the result lands in their profile.
Consent-aware studio analytics
Shapes, materials, colours and trends — aggregated only from clients who said yes.
Your studio, measured to the millimetre
Keep every client's sizes, history and preferences in one soft, private place — and let analytics quietly tell you what to restock.
- Client profiles with finger-by-finger size history
- Personal sizing links clients can complete at home
- Trends for tip models, shapes, materials, colours and revenue
