Tapered Leg Cut Angle & Offset Calculator
Calculate taper angle, rip guide offset, and jig stop positions for two-sided or four-sided furniture tapered table legs. Generate exact thousandth-inch saw cuts, maintain square apron mortise shoulders, and establish safe rip passes on table saw sleds or bandsaws.
How Do You Calculate the Angle for a Tapered Table Leg?
To calculate the angle for a tapered table leg, divide the wood removed from one face by the active taper run length, then find the arctangent: Taper Angle = arctan(Waste Per Face ÷ Taper Run). For a standard 29″ dining table leg with a 5″ straight apron section, a 2.5″ top square, and a 1.25″ base foot tapered on two inside faces, the taper run is 24″, the removal is 1.25″ per face, and the saw angle is 2.98 degrees (or an offset of 0.625″ per face on a 4-sided leg).

How to Cut Tapered Table Legs Safely on a Table Saw
Follow these four execution steps to mill mortises cleanly and saw consistent tapered faces on all four table legs:
Cut All Apron Mortises or Pocket Holes First
Never taper blanks before cutting your joinery. Mill all mortises, dowel pockets, or domino slots in the top straight section while the leg blank is completely square. Clamping an angled, tapered leg into a mortising jig leads to misaligned, out-of-square joints.
Set the Taper Jig Angle and Align Cut Line
Mark the start of the taper below the apron line and the finished foot width on the bottom. Clamp the blank into your tapering sled so that both pencil tick marks track along the saw blade teeth path.
Make the Initial Rip Passes (Faces 1 and 2)
Make the first taper cut. For 2-sided tapered legs, rotate the blank 90 degrees to cut the adjacent inside face. Save the triangular offcut wedges—they are essential reference spacers for four-sided tapers and apron clamp blocks.
Tape Offcuts Back on for Four-Sided Tapers
If tapering all 4 sides, removing faces 1 and 2 leaves the blank resting on angled surfaces. Use blue painter’s tape to reattach the offcuts back onto the blank before cutting faces 3 and 4, keeping the workpiece square and stable against your jig fence.
Why 2-Sided vs. 4-Sided Tapers Define Furniture Styles
Tapering a table leg reduces its visual weight, transitioning a bulky post into a graceful, balanced piece. Choosing whether to taper two inside faces or all four faces fundamentally shifts the architectural lines and joinery difficulty of the table.
2-Sided Taper (Shaker / Craftsman)
Tapering only the two inside faces leaves the outer faces plumb and vertical. This maintains square 90° reference corners on the room-facing sides, aligning cleanly with tabletop edges and simplify aprons.
4-Sided Taper (MCM / Hepplewhite)
Tapering all four faces creates a symmetrical pyramid slope toward the center axis. This delivers dramatic mid-century modern lightness, but requires cutting half the waste per face to achieve the same foot width.
The Apron Transition Point
Always begin the taper 1/4″ to 1/2″ below the bottom edge of the table apron. If the taper starts directly at or above the apron line, a visible, triangular gap will open up where the flat apron cheek meets the sloping leg face.
