Place a small piece of clear tape across the widest part of your natural nail bed, pressing down firmly into the sidewalls. Use a fine pen to mark each edge of your nail on the tape, remove it, and measure the distance between marks in millimetres using a standard ruler.

We offer standard sizes ranging from Extra Small (XS) to Large (L). Each size corresponds to standard millimetre widths for thumb, index, middle, ring, and pinky nails. Check our charts or message us with your specific measurements if you fall between sizes.

If you find yourself between two sizes, we always suggest choosing the slightly larger size. You can gently file down the edges of the press on nail with a standard nail file to achieve a seamless, custom fit to your natural cuticle line.

While the curvature and width across the nail bed remain consistent, different shapes such as almond, coffin, or square can feel slightly different on your hands. If you prefer a flatter or more curved fit, let us know when ordering.
