10 vs. 12 Miter Saw 7 Differences You Need To Know

selective focus on miter saw and wood

Both the 10-inch and 12-inch miter saws have some qualities about them that make each standout. However, if you are looking for a combination of durability and strength, the 12-inch miter saw is what you must choose. 

When it comes to the miter saw, everybody who uses it knows how efficient and helpful it is. No matter our job or task, it will get the work done with such precision and accuracy that it will leave you in awe. 

Today, professional woodworkers and carpenters in the field can blindly trust a miter saw to ensure that their client’s job is well done. Thousands of different brands and companies are constantly coming up with new miter saws that promise the best features. 

A question that always poses a dilemma is whether the 10-inch miter saw is better when compared to the 12-inch miter saw. Some believe that because the 12-inch miter saw is more extensive, it is more promising and works better. This battle of 10 vs. 12 miter saw is a long one.

Others are of the view that 12-inch lacks precision when it comes to the work. No matter what you are comparing, it is essential to look at every single factor before making an informed and correct decision. 

Read along to find out everything that you need to know about these two different miter saws, and then decide for yourself which one is the best. 

Difference In Price 

When it comes to the price, everybody knows who the clear winner is here. Since the 12-inch miter saw is more prominent, it costs more too. While the difference may not be that significant at times, sometimes it can be the deciding factor. 

For instance, a 10-inch miter saw should cost you anywhere between 300-450 dollars. The maximum that the price range can go up to for it is 500 dollars. However, keep in mind that you can end up paying almost 700 dollars or more for the 12-inch miter saw. 

It also depends on the face value and name of the product, which can sometimes be the deciding factor. Therefore, some brands or companies simply charge more due to their value and reputation in the market. These miter saws will always be more expensive than the rest. 

However, 10-inch is the better option if you want to save a few big bucks when buying this tool. 10 wins here in the 10 vs. 12 miter saw. 

Radius And Effect On Speed

A lot of people fail to understand that two inches can make all the difference in the world. Therefore, the final verdict is that the 12-inch miter saw has a lot larger radius. While this sounds like a good thing, in terms of carpentry, this is essentially bad news. 

A small radius— which is characteristic of the 10-inch miter saw— means that the steel blade tends to spin in circles a lot faster when compared to the speed after adding two inches. Therefore, the smaller one provides more incredible speed. 

Speed has everything to do with your task. The faster it spins, the sooner your job gets done. Not only that, but a smaller radius provides greater accuracy, precision, and smoothness than the 12-inch miter saw does. 

Therefore, keep in mind that the smaller the radius, the better it is for your work and time. 


While the ten inches have been winning the battle so far, it is not the best option in terms of every single factor. It may have a faster speed, but it does not provide the same cutting capacity that you will experience when you use twelve inches. 

Therefore, if your cutting tasks entail work in 6 inches or less, then you should not find yourself in a lot of trouble using the 10-inch saw. However, if at any point you wish to cross that limit and take on more significant tasks, know that you are going to be a little stuck. 

The cutting capacity is also somewhat dependent on the job that you are doing. If you are simply working with tiny pieces of materials and basic-level projects, then this should not be that big of an issue. But if your job entails a lot more than that, you must opt for the 12-inch miter saw without fail. 

The Power Factor 

With great power comes great responsibility, and this could not be truer for the 12-inch saw you have in mind. Since it operates with a larger blade, it is a pretty known fact that it also needs a lot more power to charge it up. 

Therefore, most 12-inch miter saws use 15 amps motor. Do you know what this means for your project? It essentially means that your cuts just became a lot more energetic, stronger, and full of finesse. 

Power means everything when it comes to woodwork. You want your cuts to speak for themselves and look amazing no matter where they are. The 12-inch blade should be your first option to do this due to the massive power that it wields in every task performed.

How Much Does It Wobble?

No matter how skilled or experienced you are, this is something where most artisans make a mistake. Wobble and deflection are essential factors when working with a miter saw. The quickest way to decide which one is better is to go back to their radiuses again. 

Since the 12-inch saw is more extensive and more prominent, this means that it has a higher possibility of getting deflected from its point of focus, and this is ruining your perfect work. Therefore, the 10-inch miter saw wins fair and square for all the right reasons when it comes to wobbling and deflection. 

What’s more, the 10-inch saw will make sure you end your task with a lot more accuracy and fewer mistakes due to this feature. It is highly imperative when it comes to how your end workpiece is going to look and feel. 


Just like your job, the making of these massive miter saws is not easy work. Therefore, you must buy one only after knowing whether it will give you good durability or break down just after one or two attempts. 

The catch here is that both of them have their benefits and disadvantages. However, the 1-inch miter saws have one slight advantage that makes them the better option for durability. 

Since they are smaller, they are easier to handle and operate. The 1-inch miter saws can be portable and easy to carry anywhere that you want to go. The 12-inch saw, on the other hand, is bigger than you can imagine. 

Therefore, the chances are that if you tend to damage or break apart one part, you will never entirely be able to use it the same way again. For this reason, it is best to choose a 12-inch one so that you do not suffer later in your job and end up making a wise decision early on itself. 


For different people, efficiency can essentially mean a lot of different things. For most, it tells how quickly they can get their job done. For others, it could also indicate how much energy consumption and electricity goes behind these huge tools. 

Therefore, it is best to make sure that you choose the right option for this factor. As discussed above, the 12-inch miter saw wields more power and is thus used to cut many materials. 

Therefore, the 12-inch saw is more efficient in this way. The larger the things you cut at a time, the more work you are likely to finish. It simply means that you can either take up more work or finish early and take more breaks. 

However, there is another factor that we must not forget when it comes to efficiency. As you must have read above, the 12-inch miter saw also requires more energy to run it. The 15 amps are comparable to the 11 or 12 amps. It means that there is also a massive difference in electricity and energy consumption. 

If you are a firm believer in getting things done with minor damage to the environment, then you should consider going for the 10-inch miter saw. It will give you a chance to use less electricity. The only issue is that it might end up taking slightly longer than you thought. 

Final Verdict 

It finally depends on the kind of project you have taken up and how quickly you want to finish it. If the job is something big requiring a lot of power, then close your eyes and spend your money on the 12-inch miter saw. 

However, if you wish to indulge in small but different projects spanned over time, then the 10-inch miter saw is perfect for you. Whatever you decide, make sure it fits your purpose! Make sure you choose well in the 10 vs. 12 miter saw.
