So, you’re constructing or re-designing your building, and you need to cut the baseboards. But you’re stuck. You have a trillion questions in your head. Where and how do you start? What materials do you need to get started? Do these questions seem familiar to you? 

Fortunately, if you have some experience and continually practice using the miter saw to cut the baseboard molding, the actual procedure of how to cut baseboard trim with a miter saw is pretty straightforward.

The differences in the various types of corner cuts used to trim baseboards to install it in the molding securely are where most people worry or get frustrated in the process.

We’ll break down the fundamentals, as well as some more technical terminologies, to help you figure out the things you need in terms of the various angled cuts you can perform and where they’re relevant when it comes to trimming and fixating the baseboard molding.

It doesn’t matter if it’s a miter or a bevel gradient, an outer or inner corner; we will cover it all and help you figure out the safest, easiest, and best approach.

What Is A Miter Saw?

According to, a miter saw is a tool to remove crosscuts and miter cuts in an object. You can lower a fixed circular saw blade onto a hard, level surface below the object to achieve it.

This sawing method is standard since you put the saw blade down into a piece to cut it rather than moving the blade around it. Consider it like chopping a vegetable with a kitchen knife and making slices until what you have left are circular fragments.

What Are The Uses Of A Miter Saw?

Miter saws are favored by some for the more basic woodworking and building needs, despite having a relatively restricted variety of uses in terms of cuts and objects utilized.

They’re handy for making doors, crown molding, gates, boxes, ledges, and other products because their purpose is to make miter cuts.

You can cut parts to precise angles within a few seconds thanks to the swift cutting action and simple angle corrections, allowing them to get through a large number of workpieces in a limited period.

They’re also helpful when you need to cut a large number of smaller sections from a more extensive work material. You can quickly outline where the cuts should be with the help of a pencil and measuring tape, and then start cutting on the slice, working your way around it in a moment or less, depending on the distance.

On building or construction sites, miter saws are popular, particularly during the framing process. In just a matter of few minutes, you can set up large miter saws to cut down wall studs and other elements, as well as to cut the appropriate angles in any of them. 

Most fence builders and roofers often carry a miter saw to the construction site, which allows them to quickly and reliably trim down fence parts and roof panels.

Miter saws may also be beneficial to other kinds of builders. Plumbers, for example, may use them to trim piping with special blades designed for the product.

How To Get Started

Here, we’ll guide you on how you can cut baseboards with your powerful miter saw in an easy and informative step-by-step method and advise you on how to mount them.

It should be a piece of cake if you’ve previously handled a miter saw. It is not difficult to handle if you have experience with the power tools.

A quick reminder before you start, be mindful of your safety. Make sure you are familiar with all the steps of precaution and follow them blindly.

Remember, this electrical tool is an extremely powerful one with a jagged, sharp circular tip, and you can use it with care. Before you bring the wood to the cutting surface, make sure the power is off and no electricity is moving to your saw.

Also, any stray hairs should be tied back, and you should avoid loose clothing. Above all, please wear protective goggles, folks! It will protect you if any sharp pieces of wood or oak fly into the air.

Now, let’s get into it, shall we?

Basic requirements

  • A measuring tape
  • A marking tool like pencils
  • A pair of safety goggles
  • A mask
  • A stud finder (optional)

5 steps to follow to cut baseboard trim

Step 1 Takedown all precise measurements

The first and most crucial step in cutting the perfect baseboards is to use your tape measure and note all the required measurements. A common saying to remember here is “measure twice, cut once.”

So remember to take measurements that are accurate to the finest detail. If you, by any chance, mistakenly cut using the wrong proportions, you might’ve just lost a decent piece of wood.

To perfect the art of taking accurate measurements, simply use a tape measure to determine the length of your walls at the foot, from one end to the other end.

Make sure you take measurements around the room. Cover all walls and all corners. It is the length of the baseboards that you must cut. It’s also a good idea to locate the studs when you’re at it because you’ll be adding the freshly cut baseboards to them.

If you have a stud finder somewhere in your toolbox, now would be an intelligent time to use it. Carefully measure and indicate where the studs when you’ve identified them.

Step 2 Inner Corner Cuts

All you’ll have to remember in this step is that you’ll have to put together 4 inner corner cuts with your trusty miter saw for the four walls of the room. Set your miter saw’s bevel to 45° and your miter to 0° at this step.

To make things easier, create markings on the stern end of the baseboard with a pencil will help easily cut down the pencil markings. You should turn the miter saw on after you’ve adjusted the miter and bevel angles and placed your board on top of the saw’s cutting table.

Holding the saw handle in one hand and the baseboard in the other, slide the blade along into the wood till you are sure it finishes cutting. You can send the blade entirely in, but don’t use excessive force. The moderate power will suffice.

Step 3 Outer Corner Cuts

Hold your miter saw at the same fixtures as before, with a 0°miter and a 45° bevel. Make markings on the baseboard with your pencil once more.

Following the dimensions, trim the baseboard so that the frontal side is slightly lengthier than the back. It will allow you to connect the corners until it is comfortably cut. Remember, take your own time and don’t put too much strain on yourself.

Step 4 Square Cuts

So, when you’re putting your baseboards together, you may want to connect them like a square pattern. To make it simpler, rather than tilting the cuts to make angled baseboard ridges, some just like to cut it symmetrically and connect them to make a vertical pair. And guess what? You can do this with the miter saw as well! Notable, isn’t it?

All you got to do here is adjust the miter to 90° and the angle to 90°. To put it another way, you’re only doing a standard cross-cut, which is one of the simplest things to do.

Step 5 Installation of the Baseboards

The installation of the baseboards is perhaps the simplest of all the steps. Put them where they’ll be and check whether they’re in the correct order. Keep in mind to always check and double-check this long before nailing the molding in place.

Fix your baseboards to the studs on the wall with the appropriate sized brad/finish nails.

Finish (also known as brad nails) are nails that are 2 inches in size. They secure every section of your baseboard molding. There is a good chance that every house has concealed electrical or telephone wires located right behind the frame. For this reason, it’s best to use nails that are approximately 12 inches long.

Summing Up

That’s it, folks. You’ve now learned how to use a miter saw in cutting baseboards and mount them like a professional. About constructing or refurbishing a house, baseboards should be as easy as ABC if you follow the instructions in this feature to measure and cut the molding.

Mastering the various angled cuts and knowing the style required for different applications can take a bit of time and practice. Just like every other skill, this is one skill that you can master over time.

All of this will become utterly automatic to you in no time if you regularly train and work with your miter saw by using waste trimmings and practice with different magnitudes for every angle cut.
