Caring for Square Toenail Shape: Mistakes to Avoid and Best Practices




The square shape is a popular choice in pedicures — clean, structured, and modern. But this shape requires special care. Unlike rounded or oval nails, square toenails are less forgiving of mistakes: incorrect trimming or filing can quickly lead to pain, ingrown nails, or aesthetic issues. MONLIS School in Munich explains how to properly care for square toenails and what mistakes to avoid.
1. What Is the Square Toenail Shape?
The square toenail has a straight free edge with clearly defined or slightly softened corners. It looks tidy and symmetrical but becomes vulnerable under pressure or poor maintenance.
Pros:
Structured and clean look
Good base for minimal or creative designs
Appears stable and tidy
Challenges:
Corners can break easily
Uncomfortable in tight shoes
Risk of ingrown nails with incorrect trimming
2. Common Mistakes in Square Toenail Care
❌ Over-rounding the corners
This weakens the nail and increases the risk of ingrown nails.
❌ Sawing motion when filing
Filing back and forth damages the nail plate and weakens the structure.
❌ Cutting nails too short
Especially on the sides, this removes protective edges and encourages ingrowth.
❌ Neglecting the side lines
Only focusing on the top can distort the entire shape — sides must stay straight and parallel.
3. Best Practices for Square Toenail Care
✔ Cut straight across
The straight free edge is the foundation of the square shape.
✔ Keep corners slightly blunt, not rounded
This reduces pressure points and helps avoid ingrown nails.
✔ Use a fine nail file (180–240 grit)
Avoid clippers or scissors when possible — file gently from edge to center.
✔ Soften nails before cutting
A warm foot bath helps prevent cracking and makes trimming safer.
✔ Use nourishing products
Daily nail oil and rich creams help strengthen nails and prevent dryness.
4. Everyday Tips to Maintain the Shape
Wear shoes with enough room for the toes
Get a professional pedicure every 4–6 weeks
Dry your feet carefully, especially between the toes
Apply moisturizing products daily
Never self-treat painful nails — seek professional help
