Square nails are one of the most classic and enduring nail shapes — featuring straight, parallel sides with a flat, even edge across the tip. This shape has been a staple in nail culture for decades, serving as the foundation for the iconic French manicure. Square nails are easy to achieve, maintain, and look polished at any length.

How to File Square Nails

Step-by-step shaping guide

Trim to your desired length — use nail clippers to cut nails straight across.

File straight across — hold the file perpendicular to the nail and file in one direction to create a perfectly flat edge.

Keep sides straight — file the sides minimally, maintaining their natural parallel lines.

Clean up corners — lightly touch the corners to remove any roughness, but keep them sharp (not rounded).

Smooth the edge — use a buffer to smooth the filed edge and prevent snagging.

Frequently Asked Questions

Are square nails out of style?

Not at all. While almond and coffin shapes dominate trends in 2026, square nails remain a timeless classic. They are consistently popular for French manicures, minimalist styles, and professional settings.

Do square nails make fingers look shorter?

Square nails don't elongate fingers like almond or oval shapes do. On very short, wide fingers, they can emphasize width. If that's a concern, try squoval (rounded corners) for a similar look with a more flattering effect.

How do I stop square nails from snagging?

Use a fine-grit buffer to smooth the corners slightly — enough to remove sharpness but not enough to round them into squoval. You can also apply a strengthening top coat to reinforce the edges.
