What is the grain size of a nail file and what does it mean?

By: Maryton

Believe you’ve seen numbers on almost every file on the market. But what do they mean? Today, the nail supply expert Maryton will explain everything to you. Just keep reading!

In fact, the numbers refer to the thickness of the grit on the surface of the nail file, or more accurately the size of each grit, as the number indicates how many grains of sand take up a square inch. The higher the number, the smoother the grain of the file, and vice versa.

If the two numbers are the same, then both sides have the same grain – if the two numbers are different, then the two sides have a different grain. For example, a 100/100 file means that both sides have the same grain. A 100/180 grit file, on the other hand, will have one side with a softer grit than the other.

Imagine a 1 inch square filled with 100 grains of sand; it will be very rough. If you take a one inch square and fill it with 240 grains of sand, it will be much smoother. So, the higher the grain, the less the nail surface is affected, the less material is removed during filing and the smoother the nail surface is after filing.

Hoping that this article has pleased you and will give you ideas! In addition, I also advise you to invest in some professional manicure kits to care for your nails!
