Let’s talk about the 12 inch miter saw first. The first thing I’d like to mention that it is extremely powerful. You can cut anything without any issue. The extreme power comes from a 15 amp motor (in most cases). And the more powerful the motor, the more cutting ability the miter saw will have. And this power will compensate for the drawbacks of speed if there is any.

On the contrary, a 10 inch miter saw has a relatively lower power capacity than a 12 inch. In the case of power, the one is a little behind the former one.


One particular advantage that separates the 10 inches one from a 12 inch is its speed. While a 12 inch has a speed of 4000 rpm, a 10 inch has 5000rpm. The reason lies behind the radius of the blade. A smaller radius will spin faster.

But like I said before, a 12 inch will compensate for its lack of speed with a higher power.

When it comes to time, 12 inch miter saw is way faster than a 10 inch miter saw. It is a real time saver when working on bulkier or heavier objects.


The 12 inch miter saw has bigger power, and bigger power means bulkier and heavier. You won’t be able to move this one easily.

But the 10 inch miter saw is lighter. Although I am not saying, that is super light but relatively lighter than 12 inch. They are pretty portable, which makes them perfect for those who work in different places.

 Cutting capacity:

Also, the blade is 12 inches in size, which means it can cut bigger objects than 10 inches. So, at a professional level, 12 inch miter saw is unparalleled. A 12 inch miter saw max cut capacity is up to 2×6/2×8.

Whereas a 10 inch sliding miter saw cut capacity is up to 4×4. It is a perfect trait for most woodworkers. Also, having only 10 inch blade, they are relatively lighter in practical use.

In comparison, a miter saw 12 inch is definitely definite ahead of a 10 inch miter saw.

 Cost and availability:

If you are a regular user, you might already know that this one is way more popular among woodworkers. The main reason is that it comes with a good price-quality ratio. You will get a more versatile yet cheaper product with a 10 inch miter saw.

As I said before, they are very common, and thus the replacement materials are available everywhere. Not to mention that the price is also affordable for most of the DIY workers.

On the contrary, the price is a bit higher in the case of this particular product. Not only the buying price, but the replacement is going to cost you a fortune.


Very often, we forget to consider one important point- steadiness.

When working on a project with machines like these, steadiness is very important. A shaky or wobbly machine will not only lower the quality but also annoy the worker.

Being a relatively lighter and smaller miter saw, 10 inch saw is less shaky and wobbly. This is totally opposite in the case of a 12 inch saw. It makes a louder sound and vibrates more.

However, there is a controversy on this matter. Many professional woodworkers have claimed that only lower-grade low cost 12 inch miter saw does that.


The 12 inch miter saw is more powerful, faster, and can pull off more rugged jobs in reality. But again, if you are not a regular user or do not work on larger projects, this one might not be for you.

But on the other side, 10 inch miter saw have a limitation in capacity. They are not as efficient as 12 inch when it comes to a larger quantity of work. So, if you are going to work on a professional level, 10 inch isn’t worth it.

Which is Better 10 inch or 12 inch Miter Saw?

I must tell you that I didn’t compare 10 vs 12 inch miter saw to prove one worse than the other. I simply wanted to highlight the best of both worlds. Now, to summarize the whole point of 10 inch vs 12 inch miter saw, the choice will depend on the job. Both the saws are great in their own way.

If you are a part-time woodworker or a DIY enthusiast, spending more money should not be the option. To get the best work with little money, a 10 inch miter saw will just be fine.

But, if you have a larger project, the 12 inch miter saw will be the right choice in a professional way. As I said, its higher power, greater capacity, and faster work mode will help you achieve your goal in no time. Also, you will get a smoother and quality result. If you get past the cost, a 12-inch miter saw is totally worth the dough.

Finally, all we want to say is that the only thing that really matters is what size miter saw do I need. All will depend on the project I am doing. The debate on 10 vs 12 Miter Saw will end at this point.

When the project is more personal than professional, a 10 inch miter saw is more than ok. It will give the freedom of carrying around and finer precision within the budget.

But if the project is massive, 12 inch miter saw should be the priority. It’s faster, powerful and saves a lot of time. Also, if you can look past the budget, get a 10 inch blade suitable for 12 inch miter saw.

Happy woodworking!
