Sandpaper grit is what makes it abrasive. Manufacturers grade sandpaper based on the size of the grit, and the grade you need depends on the job
It’s hard to think of a home improvement project that doesn’t involve sandpaper. Woodworkers use it to smooth and shape wood. Painters and refinishers need it to remove old finishes and polish new ones. Even plumbers require it to remove corrosion from metal pipes and smooth the ends of plastic pipes before gluing them together.
What Is Sandpaper Grit?
Grit measures sandpaper’s coarseness, determined by the size of the abrasive particles on its surface.
Grits Are Categorized Into Grades
While it’s theoretically possible to manufacture sandpaper grits in tiny progressions, it would be impractical and confuse customers. Consequently, grit numbers increase by standard intervals. The higher the number, the finer the grit. Coarse grits progress from 24 to 30 to 36, while fine ones rise from 600 to 800 to 1,000 and beyond.
Sandpaper Grades and Grits
The coarsest sandpaper grades and grits are generally used with machines, such as belt and drum sanders, while the finest grades come on waterproof sheets that can be combined with water for polishing.
What is the difference between sandpaper grit and sandpaper grade?
What's the Difference Between Sandpaper Grit and Sandpaper Grade? Grit size refers to the specific size of the abrasive grain (36, 60, 120, etc.), while grade is a broader term, with each grade including a range of grits. For example, medium grade includes grit sizes between 80 and 150.
What is micro grit sandpaper?
Micro grits are a class of finer abrasives. They include higher grit numbers. Micro grit-sized sandpapers are commonly used on wood and some on drywall.
What does the grit number on sandpaper mean?
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. 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.
What is sandpaper made of?
It can be made from the grains of a natural mineral called garnet, or from synthetic ones like aluminum oxide, alumina-zirco nia or silicon carbide. Irrespective of the sandpaper you work with, it must have a strong bond between the sandpaper grit and its backing material. If it doesn’t, the grit and backing material may become separated during use, ruining your application. Backing for sandpaper includes paper, cotton, polyester, rayon, PET film and rubber. Mylar is used as backing for extremely fine grits.
What is the backing material for sandpaper?
Backing for sandpaper includes paper, cotton, polyester, rayon, PET film and rubber. Mylar is used as backing for extremely fine grits.
What is a macro grit?
Macro grits are a class of abrasives that range from medium to coarse sandpaper calibers. They feature mid to low grit numbers. Macro grit-sized sandpapers are commonly used on tougher wood and metals and have a stronger clearance.
What is Sandpaper Grit?
When selecting a new sheet or disc of sandpaper for your project, you will find out that there are several different grits and abrasive materials to choose from.
How Do You Know What Grit Sandpaper To Use?

Ultra-fine sandpaper has numbers ranging from 320 to 1000. No finer types of sandpaper are usually used for DIY projects.
What Is Sandpaper Grit?
Sandpaper grit is sized by a gauge number, with lower numbers signifying larger, coarser grits. For example, #24- or #40-grit sandpaper is a very coarse, rough sandpaper, while the #1,000-grit paper is extremely fine with very small abrasive particles.
What is the difference between sandpaper grit and grit?
Sandpaper grit is sized by a gauge number, with lower numbers signifying larger, coarser grits. For example, #24- or #40-grit sandpaper is a very coarse, rough sandpaper, while the #1,000-grit paper is extremely fine with very small abrasive particles. The grit number of sandpaper is almost always clearly printed on the back of the sandpaper itself.
What is ultra fine grit?
Ultra-fine sandpaper grit is used to achieve another level of smoothness on all types of materials. With wood, ultra-fine grits usually are reserved for smoothing painted surfaces between coats. Many finer grits are used for wet sanding, which creates a fine, gritty slurry that complements the sandpaper's efforts at smoothing. #320 grit sandpaper is even used as one of the first grits when sanding down solid surface countertops .
How to use sandpaper properly?
To use sandpaper properly, you must know how to choose the right sandpaper grit. Sandpaper grits are categorized according to the coarseness of the abrasive particles used. In general, the process of preparing any surface for painting or finishing involves sanding with progressively finer grits until you reach the desired level of smoothness.
What is the difference between coarser sandpaper and finer sandpaper?
Coarser, or lower-number grit, sandpaper removes wood and other materials faster and with less effort than finer sandpaper. It does this by cutting the fibers on the material's surface.
How does sandpaper work?
It does this by cutting the fibers on the material's surface.
Does sandpaper remove scratches?
But the coarse sandpaper also leaves deep scratches. At the other end of the spectrum, very fine sandpaper removes a tiny amount of material, with the effect of smoothing the surface.
What Is Sandpaper Grit?
Sandpaper grit is the standard way to measure how rough or smooth a piece of sandpaper is. Essentially, it tells you how coarse or fine that particular sheet is. For example, number 12 sandpaper has more abrasive particles per square inch than number 80. Simply put, more grit means rougher paper, and less grit refers to smoother paper so on.
How to Choose the Right Grit Sandpaper?
When one thinks of sanding, a few key ideas often come to mind. One is that a high level of finish will likely be required. For this reason, the woodworker may go for an abrasive paper with a larger grit number, i.e., lower on the scale.
what do sandpaper grit numbers mean?
Sandpaper is graded by its ability and speed in producing a finer finish on wood or metal surface due to the size and amount of abrasive materials ( grit).
How Is Sandpaper Grit Measured?
The grits on sandpaper are measured by a check number , with the least numbers connoting bigger. For instance, 24 or 40 grits sanding paper is an exceptionally coarse, harsh sanding paper, while the 1000 grits sandpaper is amazingly fine with little rough elements. The grit's number of sandpaper is quite imprinted on the rear of the sandpaper. The grit numbers extend from 24 as far as possible up to 1000, albeit a great many people will not ever utilize the grit at the highest or base of the gage.
How to measure sandpaper grit?
It is measured by counting how many lines per inch (LPI) can be felt with one square inch of the sandpaper sheet. They range from 30 to 2500, so there's something for everyone! The higher the number, typically means that it will cut faster and last longer - but not always. For instance, if you're using a coarse sandpaper on wood then a lower grit might work better because it won't take off too much of your material when you go over an area. So don't just assume because it's more expensive that it'll do everything you need in one pass!
What is the grit scale?
The grit system is a standard, internationally recognized scale that measures sandpaper to its finest levels from its coarsest. It ranges in value from the super coarse (150-grit) to the ultra-fine (12,000 and above). Most people associate this number with the US Standard for grading papers, which also follows a similar format. For example, the 100-grit paper refers to both 100-grit paper and 100-point coated bond paper under the US Standard.
Why is sandpaper grade low?
A low grade number indicates that there are bigger pieces in the blade , while a higher one means more small ones. Many sandpaper manufacturers do not specify sandpaper grade, only sand paper grit. The reason for this is that sandpaper grade cannot be specified without knowing the sanding surface's (wood, metal etc.) inherent hardness. This is because fine particles easily wear out and fall off in harder materials, while a coarse sandpaper can stand up to tougher resistance better. For example, using 100 grit sandpaper on wood will take longer than it would if 120 were used instead, since the higher number denotes more sanding power which helps remove material quicker.
