How are sandpaper grits defined?
The grit of sandpapers is a rating of the size of abrasive materials on the sandpaper. The higher grit number is equivalent to a finer abrasive, which creates smoother surface finishes. Lower grit numbers represent coarser abrasives that scrape off materials much quicker.
What is FEPA sandpaper?
The most common system used in the U.S. measures the grits of sandpaper in an ascending order, with the finest grit getting the highest number and coarser grits having lower numbers. In Europe, the Federation of European Producers of Abrasives (FEPA) has its own system for grading grits of sandpaper.
What is FEPA grit?
FEPA (The Federation of the European Producers of Abrasives) regulates abrasive standards for Europe. In order to avoid confusion, the designation “F” is used for sharpening stones and wheels (the classification is called FEPA-F), and for sandpaper abrasives the designation “P” (FEPA-P) is used.
What is FEPA standard?
FEPA Standards defines the mean diameters of macrogrits as a range and not a single value. The particle size distribution of macrogrits is determined by sieving, while the microgrits have been measured by sedimentation (photosedimentometer).
What does 60 grit sandpaper mean?
Rather, the number scale refers to the number of holes per square inch in the screens that are used when sieving the abrasive grains during the sandpaper’s manufacture. For example, in 60-grit sandpaper, the abrasive particles used in the paper were sieved through a screen that had 60 holes per square inch.
What are the different sandpaper grits?
Sandpapers are commonly graded as coarse (40 to 60 grit), Medium (80 to 120), Fine (150 to 180), Very Fine (220 to 240), Extra Fine (280 to 320) and Super Fine (360 and above). Sanding with progressively finer grits removes the scratches left by the previous paper and eventually leaves a smooth finish.

How do I choose sandpaper grit?
Sanding wood
- For stripping wood, use an extra coarse grit of 40.
- For sanding wood, use a medium grit of 80.
- For finishing wood, use a fine grit of 120.
- For super finishing wood, use an extra fine grit of 180.
How is the grit of sandpaper measured by FepA?
In the chart below, the grit is measured via both the CAMI (Coated Abrasives Manufacturing Institute) and FEPA (Federation of European Producers of Abrasives) standards, the latter of which is preceded by a “P.” There are two main subdivisions, micro and macro, with many more gradations included.
How does the numbering system for sandpaper work?
Actually, there is more than one sandpaper numbering system. The most common system used in the U.S. measures the grits of sandpaper in an ascending order, with the finest grit getting the highest number and coarser grits having lower numbers.
What does the grit number mean on a sandpaper?
The grit of sandpapers is a rating of the size of abrasive materials on the sandpaper. The higher the grit number is equivalent to a finer abrasive, which creates smoother surface finishes. Lower grit numbers represent coarser abrasives that scrape off materials much quicker.
What is the finest sandpaper grit?
The most common system used in the U.S. measures the grits of sandpaper in an ascending order, with the finest grit getting the highest number and coarser grits having lower numbers. In this system, 16-grit is one of the coarsest grades of sandpaper, while 3,000-grit is one of the finest.
