Choose a miter saw when the recurring job is cutting boards to length or angle and the exact workpiece fits the saw at that angle. Choose a table saw when the recurring job is ripping material to a repeatable width and you can support the entire feed path. Do not choose from project labels alone: a board that fits a square miter cut may not fit at 45 degrees, and a table saw’s rip number does not create the missing infeed and outfeed room.

Our four-model audit found a useful boundary. The sampled 12-inch sliding miter saws accept about 13.5 inches of width at a square crosscut, but only about 9.5 inches at a 45-degree miter. The sampled wheeled jobsite table saws offer 30 to 32.5 inches of right-side rip capacity and the same listed depth limits: 3-1/8 inches at zero bevel and 2-1/4 inches at 45 degrees.

Those figures are feasibility checks, not performance rankings. They do not establish accuracy, cut quality, dust capture, durability, or ease of use.

The four-model cut-limit map

Verified against current U.S. manufacturer records and public safety guidance on September 1, 2026.

Exact model Documented cut envelope Support and safeguard facts Stop rule
DEWALT DWS780 At 0-degree miter: up to 13.75 in wide with 3.0 in resulting height, or 4.4 in high with 9.1 in resulting width. At 45-degree miter: up to 9.6 in wide with 3.0 in resulting height Vertical clamp included; manual documents four bench-mounting holes; 50 degrees left and 60 degrees right miter range The workpiece must pass the exact height-width pair at the intended angle; blade diameter is not the capacity
Bosch GCM12SD 3.5 x 13.5 in at square miter and bevel; 3.5 x 9.5 in at 45-degree miter and zero bevel 40 in of integrated left-to-right support, vertical clamp, lower guard, and motor brake; listed at 65 lb External support is still required when the stock extends beyond the integrated base; do not use it to rip solid timber
DEWALT DWE7491RS 32.5 in right-side rip capacity; 3-1/8 in cut depth at zero bevel and 2-1/4 in at 45 degrees Rolling stand, guard assembly, riving knife, push stick, rip fence, and miter gauge included; table is 21-7/8 x 26-3/8 in Rip capacity does not replace stock support; an included miter gauge does not make a long-board crosscut the right operation
Bosch 4100XC-10 30 in rip capacity right and 8.5 in left; 3-1/8 in cut depth at zero bevel and 2-1/4 in at 45 degrees Barrier guard, riving knife, anti-kickback pawls, push stick, auxiliary fence, and miter gauge included; 58 lb bare and 94 lb with standard equipment and stand Count the 94 lb system and full stock path, not just the 27 x 32.5 x 13 in machine dimensions

The DEWALT DWS780 row uses the current instruction manual’s paired capacity table , not the shorthand “2x14” label. Nominal lumber names and actual cut dimensions are different facts.

Gate one: decide whether the cut is across or along the stock

A miter saw brings the blade through stationary stock held against a fence. That is the natural route for crosscuts, miters, bevels, and compound trim cuts. A table saw keeps the blade in the table while the operator feeds stock past it. That is the natural route for straight rip cuts and repeatable widths.

This is a harder boundary than “which saw is more versatile.” The CCOHS miter-saw guidance says not to cut solid timber along the grain. It also says the stock should sit firmly against the fence rather than being cut freehand. If the planned operation is a rip, the miter saw fails before brand, motor, or blade size enters the decision.

A table saw can crosscut with the correct setup, but that does not make every crosscut sensible. OSHA’s table-saw guidance specifically advises avoiding long-board crosscuts because the hand pressure required near the blade and the moving board can create hazards. A miter gauge in the box is an accessory, not a waiver of that boundary.

Gate two: test the actual dimensions at the actual angle

“It cuts a 2x14” is not enough. A capacity is a height-width pair, and the pair changes with miter and bevel angle.

The two sampled miter saws cluster tightly at a square crosscut: 13.75 inches maximum width on DWS780 and 13.5 inches on GCM12SD. At a 45-degree miter, those figures fall to 9.6 and 9.5 inches. That means a wide board can pass the straight-cut check and fail the angled-cut check on the same saw.

Use this sequence before buying:

  1. Record the workpiece’s actual thickness and width, not its nominal name.
  2. Record the required miter and bevel angles.
  3. Find that exact angle combination in the model’s current manual.
  4. Reject the saw when either dimension exceeds the documented pair.

The table-saw check uses different axes. First compare material thickness with cut depth. Then compare the target finished width with the correct left- or right-side rip limit. A 32.5-inch right rip figure does not say that every large sheet is controlled throughout the cut, nor does it describe the room needed around the saw.

Gate three: draw the support path, not just the footprint

The old ToolForge pages treated a miter saw as the automatic small-space winner. The sources support a narrower conclusion: the two machine classes demand space in different directions, and both need stock support.

Long stock on a miter saw extends left and right. Bosch lists 40 inches of integrated support across the GCM12SD, but that is not a promise that a long board becomes self-supporting. CCOHS says to attach the saw firmly to a workbench or rigid frame, and the exact manual remains controlling for mounting and work support.

Table-saw stock travels toward and away from the blade. OSHA says to leave sufficient clearance and properly support cut and uncut stock, scrap, and the finished piece. Measure the complete path before calling a wheeled stand “portable.” The Bosch table-saw package is listed at 94 pounds with standard equipment and stand, compared with 65 pounds for the sampled Bosch miter saw. That exact pair supports a transport difference; it does not prove that every miter saw is lighter than every table saw.

If neither deployed path fits, do not force the choice. Our circular saw or miter saw guide covers a different mobile-tool decision, and the track-saw versus table-saw guide addresses panel work without assuming a permanent table-saw lane.

Gate four: buy the safeguard package, not a bare capability claim

Both sampled table-saw packages include a guard assembly, riving knife, push stick, fence, and miter gauge. Bosch also names anti-kickback pawls and an auxiliary narrow-workpiece fence. OSHA identifies guarding, a spreader or riving function, anti-kickback measures, correct blade choice, stock support, and push-stick use as material controls.

Treat missing equipment as an unresolved purchase, not as a score penalty you can trade against extra capacity. Check the exact manual, included-items list, and replacement-part route before ordering. If a listing hides the guard, riving knife, clamp, support, or model identity, reject the listing until those fields are resolved.

The miter-saw route has its own non-negotiables. CCOHS says to keep guards in place, secure the machine to a rigid support, cut one workpiece at a time, and keep stock solidly against the fence. It also gives a general instruction not to cut pieces shorter than 20 cm (8 inches). Follow the exact manufacturer’s manual and a competent safety procedure for the specific cut; this comparison is not operating training.

Which saw should you buy first?

Buy the miter saw first when

  • the recurring operation is crosscutting boards to length or cutting trim angles;
  • the widest and tallest workpieces pass the exact capacity pair at the required angle;
  • you can support long stock left and right; and
  • the saw can be secured at a suitable work height with its guard and clamp route intact.

The exact-model searches for the DEWALT DWS780 and Bosch GCM12SD are labelled searches, not verified direct product pages. Confirm the model and manual before ordering.

Buy the table saw first when

  • the recurring operation is ripping boards or panels to repeatable widths;
  • material thickness and target width pass the exact depth and rip-capacity gates;
  • the infeed, blade, and outfeed path can stay clear and fully supported; and
  • the guard, riving knife, push stick, fence, and required anti-kickback controls are present and understood.

The DEWALT DWE7491RS search and Bosch 4100XC-10 search are also exact-model searches rather than verified direct ASIN routes.

For a broader model-selection pass after the machine class is settled, use the miter saw buying guide for beginners or the table saw buying guide for beginners . Do not let a model roundup reopen the cut-direction decision you have already resolved.

Method and limits

This is a paired specification and safety-boundary audit, not a hands-on test. We retained seven source records: current product or manual evidence for DWS780, DWE7491RS, GCM12SD, and 4100XC-10, plus OSHA table-saw and CCOHS miter-saw guidance. We normalized cut-capacity pairs, rip limits, cut depth, table or support dimensions, weight where comparable, included safeguards, and documented stop rules.

We did not test accuracy, cut quality, dust capture, noise, vibration, durability, setup time, transport, or stock handling. The four corded U.S. models are an illustrative sample, not a market census. Manufacturer claims remain attributed. Machine dimensions are not a complete workspace measurement, and occupational-safety guidance is not a consumer product ranking.

The useful result is a decision sequence: cut direction, exact dimensions at the required angle, complete stock-support path, then the safeguard package. If any gate fails, choose a different method or model rather than asking a broad category label to cover the gap.
