Straight sides with a flat, even edge — the timeless shape that never goes out of style
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. Their flat, wide tip provides excellent surface area for nail art while maintaining structural strength.

The straight sides add visual width, making narrow nails appear more balanced.
The flat tip is the classic canvas for French tips and creates the cleanest white line.
Easy to file at home and doesn't require professional shaping.
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.

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.
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.
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.
