10-inch vs 12-inch Miter Saw: How Different Are They?

In Brief: 10-inch vs 12-inch Miter Saw

10-inch miter saws are more affordable, portable and have smoother cuts due to faster RPM. While 12-inch miter saws have a higher cutting capacity but are bulkier and come at a bigger price tag.

Whether you are a professional or a hobbyist, the miter saw is a tool that if picked out correctly, will last you many, many years so it’s important that you do not make an overhasty decision. 

Miter saws come in many different varieties and sizes with many reputable brands to pick from. The first and presumably most important decision ahead of you is the size of the blade. These tools come in sizes starting as small as 7 1/4” and gong all the way up to 20”. However, the most commonly used are the 10 and 12-inch blades. 

Now you might be thinking: how prominent can the 2-inch difference in these two blades be? The answer is; very. 

Before deciding on which size blade you want to get, you should start by figuring out what you want to get out of it. Both of these miter saw sizes are very helpful in woodworking and carpentry and they both come with their own pros and cons.
