A wood router design pattern is a template that guides your router so it cuts the same shape again and again. In this guide, you will learn how to plan a pattern, size it for your bit and base, and build a template that produces clean, repeatable cuts. The method works for inlays, signs, decorative grooves and repeat parts for furniture.

Step 1: Draw the Pattern Full Size

Start with a full-size drawing on graph paper or in a drawing program set to actual dimensions. Mark the finished cut line, not the template edge. Keep the design simple at first, using straight lines, arcs and circles, because curves with tight radii are harder to route cleanly.

Step 2: Account for Bit Diameter and Base Offset

The router bit does not cut along the edge of the template. It cuts along the path of the bearing or the guide edge, so you need an offset. Use this rule:

  • Outside cut (bearing on template edge): Offset the template outward by the bit radius.
  • Inside cut (bearing running in a cutout): Offset the template inward by the bit radius.
  • Bearing-guided bit: The bearing diameter sets the offset. The bit cutting diameter is not the reference.

Measure your bit and bearing with calipers before you draw the final template. Many shops mark the offset on the drawing so they can check it later.

Step 3: Build the Template

Cut the template from 1/4-inch or 1/2-inch plywood, MDF or hardwood, depending on how often you plan to reuse it. Use a bandsaw or jigsaw to rough out the shape, then smooth the guide edge with a flush-trim bit or a spindle sander. The guide edge must be smooth and free of flats, because every bump transfers to your workpiece.

Checklist before you cut

  1. Verify the offset with a test cut in scrap.
  2. Clamp the template firmly so it cannot shift.
  3. Mark the start point and the direction of travel.
  4. Set the depth in passes of no more than about 1/4 inch for hardwood.

Step 4: Rout in Passes and Check Your Work

Route in a clockwise direction on outside edges and counterclockwise on inside cuts, so the router feeds against the bit rotation. Take light passes, increasing depth gradually. Stop and inspect after each pass. Tear-out on the exit side is common, so feed slightly slower where the grain changes direction.

Common Mistakes

  • Forgetting the bearing offset, which leaves the cut too large or too small.
  • Using a warped or uneven template edge.
  • Taking too deep a pass, which causes burning and bit deflection.
  • Letting the template slip, especially when clamping only one side.
  • Skipping a test cut in scrap that matches your final stock.
  • Template-guide bushing set: Lets you swap guide sizes without remaking the template. View on Amazon
  • Flush-trim router bit with bearing: Trims template edges cleanly so the guide stays smooth. View on Amazon
  • Digital calipers: Confirms bit and bearing diameter before you calculate offset. View on Amazon

FAQ

Can I use one template for different bit sizes?

Only if you change the bearing or guide bushing to match the offset you designed for. Otherwise, the cut will be off by the difference in diameter.

What material works best for a reusable template?

Many woodworkers use 1/2-inch MDF or hardwood because they hold their edge well. Plywood works for shorter-term projects.

Do I need a router table for template routing?

No. A handheld router with a bearing-guided bit works well for template routing. A table is more useful for edge profiles and repetitive work.

Conclusion

A solid wood router design pattern comes down to accurate drawing, correct offset for your bit and bearing, and a smooth template edge. Test your offset in scrap before routing the final piece. With these steps, your patterns will produce consistent results across repeat cuts.
