Nail File Grit Guide: Why the 100/180 Grit File is the Essential Tool

The guide breaks down grit sizes and why a dual-sided 100/180 file is the most versatile tool.

Written by: 3 min read

The right nail file directly affects the health and strength of your nails. The grit number on your file indicates its coarseness. Each coarseness is best for different uses. Here's your guide to understanding nail file grit sizes.

What is Nail File Grit?

"Grit" refers to how coarse or fine a nail file is:

  • Lower numbers (80-100) mean a coarser file, ideal for shaping thicker, stronger nails or acrylics.

  • Medium numbers (120-180) provide versatile shaping and smoothing for both natural and artificial nails.

  • Higher numbers (240 and above) are fine-grit files for gentle smoothing, polishing, and finishing touches.

Why Choose a 100/180 Grit Nail File?

A 100/180 nail file combines two grit levels in one convenient tool:

  • 100 Grit (Coarse Side): Perfect for initial shaping, shortening nails quickly, and effectively handling gel or acrylic enhancements.

  • 180 Grit (Fine Side): Ideal for smoothing edges, refining shape, and gently preparing natural nails for polish or treatment without damage.

FAQs: Everything You Want to Know

Q: Can I use a 100 grit file on my natural nails?
A: The 100 grit side is coarse and can quickly thin out natural nails, so use it primarily for shortening and initial shaping.

Q: How often should I replace my nail file?
A: For personal use, a good quality nail file typically lasts a 5-10 uses. However, replace it once it shows significant wear or isn't filing effectively. With Theniya's files, you'll be able to easily see when the file wears down due to use.

Q: Are washable nail files better?
A: Washable files, like Theniya’s, offer excellent hygiene benefits as you can clean them regularly, extending their lifespan and ensuring sanitary nail care.

Q: Can I use the same file for toenails and fingernails?
A: Yes! When you’re using your own file, it’s hygienic—as long as you clean it between uses. The coarse side is especially helpful for toenails since they tend to be thicker. We still recommend washing your file regularly to maintain cleanliness and effectiveness.

Q: What is Theniya’s 100/180 professional grit file made of?
A: Theniya’s nail file uses a high-quality abrasive surface bonded to a firm core. The materials are are both durable and washable.

Q: Why shouldn’t I use metal files?
A: Metal files can cause splintering and peeling by roughening nail edges. Grit-based files offer a gentler, smoother finish. 

Q: What about glass nail files—are they good?
A: Yes! Glass nail files are gentle on natural nails and offer a smooth finish that helps prevent splitting. They last a long time and are easy to sanitize. But they are mostly great for finishing touches but not ideal for major shaping or shortening. Dual-sided nail files are more versatile.

Q: What’s the difference between buffing blocks and nail files?
A: Nail files shape and shorten the nails, while buffing blocks smooth, polish, and add shine to the nail surface without removing much length.
