The short answerFor trim and small projects, a 10 in single-bevel compound miter saw at $130 to $250 does the job. If you cut shelving or wide boards, get a 10 in sliding saw for $250 to $500. Swap in a 60 to 80 tooth blade for trim.
What to buy
Trim and small projects
10 in single-bevel compound miter saw, 15 amp
Crosscuts a 2x6 and handles baseboard, casing and picture frames. Wider boards need a flip and a second cut.
$130 to $250

10 in sliding compound miter saw
The head slides on rails to cut boards up to about 12 in wide, like shelving and stair treads. It costs more, and most need clear space behind the saw.
$250 to $500
See options on Amazon →Crown, tall trim and posts
12 in dual-bevel sliding miter saw
Cuts 4x4 posts in one pass and tilts both ways, so long trim stays put. It weighs 50 lb or more, and blades cost more.
$400 to $800

60 to 80 tooth carbide blade
The cheapest way to get smooth, chip-free trim cuts from a budget saw. Fine-tooth blades cut slower in thick framing lumber.

What the numbers mean
- Blade size
- A 10 in saw crosscuts about 5-1/2 in wide without sliding, and a 12 in saw about 7-1/2 in. 10 in blades cost less and are sold everywhere.
- Miter and bevel
- A miter cut swings the blade left or right across the board. A bevel cut tilts the blade sideways, and a compound saw does both at once.
- Single vs dual bevel
- Single bevel tilts one way, so you flip the board for the opposite cut. Dual bevel tilts both ways, which saves time on crown and long trim.
- Sliding
- The saw head glides forward on rails to cut wider boards. A 10 in slider cuts about 12 in wide.
- Tooth count
- Stock blades often have 24 to 40 teeth, which suits framing lumber. 60 to 80 teeth leaves clean edges on trim.
What not to pay for
- A 12 in saw for baseboard
It's heavier and pricier, and the blades cost more. A 10 in saw handles nearly all household trim.
- Paying extra for a laser
Lasers drift out of line and wash out in sunlight. A pencil mark and a test cut on scrap is more reliable.
- Trusting the factory angles
Check 90 and 45 degrees with a square before your first project. Most saws have adjustment screws if they're off.
Hold or clamp the board tight to the fence, with your hands at least 6 in from the blade. Let the blade reach full speed before cutting, and let it stop before you lift it. Wear eye and hearing protection, and never cross your arms over the cut line.
Questions
Should I buy a 10 in or a 12 in miter saw?
10 in for most people. It's lighter and cheaper, and it handles trim, 2x4s and 2x6s. Go to 12 in if you cut 4x4 posts, tall baseboard or big crown often.
Do I need a sliding miter saw?
Only if you cut boards wider than about 6 in. For baseboard, casing and 2x4s, a non-sliding saw is lighter, cheaper and takes less room.
Is dual bevel worth it?
For a lot of crown molding or long trim, yes, because you tilt the saw instead of flipping a 12 ft board. For occasional projects, single bevel works and saves $50 to $150.
