How to Align a Table Saw: A Step-by-Step Guide — Best overall

By Finlay Connolly

Why This Is Worth an Afternoon of Your Time

A table saw that’s out of alignment doesn’t always announce itself. It might just show up as burn marks along your cuts, a bit more resistance pushing wood through than feels right, or edges that never quite come out as clean as you’d expect. Left unaddressed, it’s also one of the more common contributors to kickback, since a misaligned blade or fence pinches the wood instead of letting it pass through cleanly.

The good news is that alignment is something you check occasionally, not constantly. Once it’s dialed in, a table saw generally holds that setting until something knocks it out, a hard impact, moving the saw, or just years of normal use. This guide walks through the full process in the order it actually needs to happen.

Two Saw Designs, Two Different Adjustment Methods

Before touching anything, it’s worth knowing which type of saw you have, since the actual adjustment process is different depending on the answer. On cabinet-style saws, the blade and motor assembly, called the trunnions, mount directly to the saw’s base. To adjust alignment on this style, you loosen the table itself and tap the table into position, since the blade assembly is the fixed reference point.

On contractor, hybrid, and jobsite saws, the trunnions typically mount to the underside of the table instead. That flips the adjustment around: the table and its miter slots are the fixed reference point, and you loosen and tap the trunnion assembly to bring the blade into alignment with it. Getting this backwards, trying to move the table on a saw where the trunnions are what actually need adjusting, won’t get you anywhere.

If you’re not sure which category your saw falls into, our Cabinet Saw vs Hybrid Saw guide covers exactly how to tell the difference by checking where the trunnions actually mount.

Step 1: Align the Blade to the Miter Slot

The miter slot is your fixed reference point for this entire process, so this step comes first, before touching the fence at all. Everything else gets aligned relative to the miter slot, not the other way around.

1. Unplug the saw. Do this before anything else, every time.
2. Raise the blade to its full height and pick one tooth, marking it with a felt-tip pen so you’re measuring from the same exact point throughout the process.
3. Rotate that marked tooth to the front of the blade, positioned just above the table.
4. Place an adjustable combination square in the miter slot closest to the blade, and slide it until the end of the square just touches the marked tooth. Lock the square in place.
5. Rotate the blade by hand so the same marked tooth is now at the back of the table, in the same position relative to the blade’s diameter.
6. Slide the locked square back along the miter slot to the rear position and check the gap between the square and the marked tooth. If there’s a gap, measure it with a feeler gauge.
7. If the measurements at front and back match, your blade is aligned. If they don’t, the blade needs adjusting before you go any further.

One detail worth getting right: measure from the miter slot on the side the blade tilts away from, not the side it tilts toward. Measuring from the wrong side means any correction you make will actually throw the alignment further off rather than fixing it.

To make the correction, loosen the mounting bolts, either the table’s bolts on a cabinet saw, or the trunnion’s bolts on a contractor or hybrid saw, by about a half to three-quarters of a turn. Use a dead blow hammer, or a hammer and a punch for trunnion adjustments, to gently tap the loosened part in the direction needed. Small taps only. Recheck your measurement with the square after each tap, and repeat until front and back measurements match. Once they do, retighten the mounting bolts fully.

Using a Dial Indicator for More Precision

The tooth-and-square method above is accurate enough for the vast majority of woodworking, but if you want a more precise, repeatable measurement, a dial indicator mounted to your miter gauge is the upgrade. Clamp the dial indicator to a small wood block attached to your miter gauge, angled so the tip lightly touches one side of the blade near a marked tooth. Zero the indicator, then slide the miter gauge down the slot so the indicator now touches the same tooth at the opposite end of the blade. Any difference from zero tells you exactly how far out of alignment the blade is, in thousandths of an inch, rather than just a visible gap.

This method depends on your miter gauge fitting snugly in the slot without wobble. If your gauge has any play, apply light, consistent pressure toward the blade side as you slide it, so you’re not introducing your own measurement error on top of the blade’s actual alignment.

Step 2: Align the Fence to the Blade and Miter Slot

Only move on to the fence once the blade itself is properly aligned to the miter slot. Aligning the fence first, before the blade, means you’re aligning it to a reference point that’s about to change, which wastes the work.

• Loosen the bolts that secure your fence to its rail system, generally found on top of or alongside the fence body.
• Slide the fence over until it sits directly against the miter slot.
• Check alignment along the full length of the slot. A simple, genuinely effective method is to run a finger along the miter slot’s edge closest to the fence, checking that the fence face stays flush against your finger all the way from front to back.
• For a more precise check, use a square or a straightedge to measure the gap between the fence and the miter slot at the front and rear separately, the same front-and-back comparison method used for the blade.
• Adjust the fence position until front and rear measurements match, then retighten the mounting bolts.

Why a Slight Toe-Out Is Actually Safer Than Perfect Parallel

This surprises a lot of people the first time they hear it: a fence that’s angled very slightly away from the blade at the back, rather than perfectly parallel or angled toward the blade, is the safer setup. If the fence toes in toward the blade even slightly, the workpiece gets pinched between the fence and the blade as it passes through, which is a real kickback risk. A fence toed out very slightly gives the cut a little extra clearance instead. This doesn’t mean aiming for a large gap, just that erring very slightly toward too much clearance rather than too little is the safer mistake to make if you can’t get it dead-on perfect.

Don’t Skip the Bevel Stops

Once the blade and fence are aligned at 90 degrees, it’s worth checking your bevel stops too, since a lot of saws drift here over time without anyone noticing until a beveled cut doesn’t come out right. Tilt the blade to a full 45-degree bevel and repeat the same front-and-back measurement process against the miter slot. If the blade’s tilt indicator doesn’t actually read 45 degrees when the blade is genuinely at 45 degrees, most saws let you loosen a small screw on the indicator itself and reset it to match reality, separate from adjusting the blade’s actual angle.

A Cheap Trick for Checking Square at the Table Center

When checking whether your fence sits at a true 90 degrees to the table, always check at the center of the table rather than out on the extension wings, since wings can dip slightly even on an otherwise well-tuned saw and will give you a false reading. If you don’t have a dial indicator handy, a couple of pennies stacked in the miter slot with a thin strip of wood laid across them creates a simple, improvised lip you can measure against, a trick more than one experienced woodworker swears by for quick checks between more thorough tune-ups.

How Often You Actually Need to Do This

Not often, and that’s the good news. Once a saw is properly aligned, it typically holds that setting through normal use. The times worth rechecking are after moving the saw to a new location, after any noticeable impact or hard kickback event, if you notice new burning or binding during cuts, or simply as part of an annual tune-up if the saw sees regular use. Checking the fence specifically is worth doing a bit more often than the blade, since the fence gets bumped and adjusted far more frequently in day-to-day use.

It’s also worth knowing the difference between misalignment and true blade wobble, since they’re often confused but need completely different fixes. Our How to Fix Table Saw Blade Wobble guide covers that separate issue if your blade seems to be physically wandering rather than just sitting at the wrong angle.

Common Mistakes People Make

• Aligning the fence before the blade, which means aligning it to a reference point that’s about to move
• Measuring from the wrong side of the blade relative to its tilt direction, which makes corrections worse instead of better
• Checking squareness out on the extension wings instead of at the table’s center
• Forcing large adjustments in one motion instead of small taps with frequent rechecks
• Forgetting to recheck the fence after making any adjustment to the blade itself
• Skipping the bevel stop check and only verifying alignment at 90 degrees

Frequently Asked Questions

Should I align the blade or the fence first?

Always the blade first. The miter slot is your fixed reference point, and the blade needs to be aligned to it before the fence is aligned to the blade. Aligning the fence first means you’re working against a blade position that’s about to change.

How do I know if my table saw needs alignment?

Common signs include burn marks along your cuts, extra resistance feeding wood through the saw, inconsistent cut width, or an uptick in binding or kickback. If your saw is new, was recently moved, or took an impact, it’s worth checking proactively rather than waiting for a problem to show up. A wobbling blade can cause similar symptoms, so if a quick alignment check doesn’t explain what you’re seeing, our How to Fix Table Saw Blade Wobble guide covers that separate possibility.

Do I need a dial indicator to align my table saw?

No, though it’s a worthwhile upgrade if you want more precision. The combination square and marked-tooth method described in this guide is accurate enough for the vast majority of woodworking and doesn’t require any specialized tools beyond a square and a feeler gauge.

Is it better for the fence to be perfectly parallel to the blade, or slightly angled?

A very slight toe-out, meaning the back of the fence sits a hair farther from the blade than the front, is generally considered the safer setup compared to perfectly parallel, and far safer than any amount of toe-in. Toeing in toward the blade risks pinching the workpiece against the blade during a cut, which is a real kickback risk.

Does blade tilt direction affect how I align my saw?

Yes, specifically in which side of the miter slot you should measure from during blade alignment. You want to measure from the side the blade tilts away from, not toward. Our Left-Tilt vs Right-Tilt Table Saws guide covers how tilt direction affects several other parts of how a saw is set up and used, beyond just this measurement detail.

The Bottom Line

Table saw alignment isn’t complicated, it just needs to happen in the right order: blade to miter slot first, then fence to blade, then a check of the bevel stops. Small, careful adjustments with frequent rechecks beat one big correction every time. Once it’s dialed in, you shouldn’t need to revisit it until something knocks it out, a move, an impact, or just enough time that it’s worth a routine check.
