Edge Grain Strip Calculator

Calculate strips needed for an edge grain cutting board glue-up

Units
This sets the default unit for entries and the unit results lead with. You don't have to commit to one system — type a suffix on any field to mix freely (e.g. 300mm, 12in, or 1-1/2") and it'll be read in that unit no matter which button is selected. Switching this toggle only re-expresses the fields you left without a suffix.

Strips run along the length. Strip count is determined by the width.

Typical cutting board thickness is 3/4" to 1-1/2"
The width of each individual strip you'll rip from your lumber
Standard table saw blade kerf is 1/8" (0.125"). Thin-kerf blades are 3/32".

Understanding Edge Grain Cutting Boards

An edge grain cutting board is made by ripping lumber into strips and gluing them together with the edge (the narrow face of each strip) facing up. This creates the classic striped pattern you see on many cutting boards and butcher blocks. It's one of the most popular and practical cutting board constructions.

How Edge Grain Construction Works

The process starts with a piece of lumber, typically 3/4" to 1-1/2" thick. You rip the board into strips of your desired width on the table saw, then rotate each strip 90 degrees so the edge faces up. The strips are glued together side by side to create the finished board. The thickness of your original lumber becomes the thickness of your finished cutting board.

Because the wood grain runs along the length of each strip, an edge grain board is strong and durable. It resists splitting and is easier to maintain than end grain. It also shows off the natural color variation between strips, especially when alternating wood species.

Why Strip Count Matters

Getting the strip count right before you start cutting is essential. Every cut you make with a saw blade removes a thin sliver of wood (the kerf), and those losses add up across many cuts. If you don't account for kerf loss and cleanup allowance, your finished board will end up narrower than planned.

This calculator figures out exactly how many strips you need, how much raw material you'll consume (including kerf), and the total board feet required. You can take these numbers straight to the lumber yard or your stock rack.

The Math Behind the Calculator

The calculation follows these steps:

  1. Add cleanup allowanceto the finished width. This accounts for the material you'll remove when trimming the glued-up panel to final size and sanding the edges smooth.
  2. Divide by strip widthand round up to get the number of strips. You always round up because you can't use a partial strip.
  3. Calculate kerf loss:you make one fewer cut than you have strips (for example, 8 strips require 7 cuts). Multiply the number of cuts by your blade's kerf width.
  4. Total raw width is the sum of all strip widths plus all kerf losses. This is the width of lumber you need before making any cuts.
  5. Board feetare calculated from the raw width, board length, and thickness using the standard formula: (Thickness × Width × Length) ÷ 144.

Choosing Your Strip Width

Strip width affects both the look and the difficulty of your build:

  • Narrow strips (3/4" to 1"): Create more visual interest with tighter stripe patterns. Require more cuts and more gluing surfaces, which increases kerf loss and glue-up complexity.
  • Medium strips (1-1/4" to 1-1/2"): A good balance of appearance and ease. This is the most common range for cutting boards.
  • Wide strips (1-3/4" to 2"): Fewer cuts, faster glue-up, and lower material waste. The stripe pattern is subtler.

Cleanup Allowance: How Much Do You Need?

After gluing up your strips, the panel will need to be jointed, planed, and trimmed to final dimensions. The cleanup allowance covers:

  • Edge trimming:Squaring up both edges after glue-up (1/16" to 1/8" per side)
  • Glue squeeze-out: Removing dried glue from the faces and edges
  • Sanding: Final surface preparation removes a small amount of material
  • Alignment corrections: Strips that shift slightly during clamping need to be flushed

For most projects, 1/4" total cleanup allowance is sufficient. If you're working with difficult-to-align strips or rough lumber, increase to 1/2".

Tips for a Successful Edge Grain Glue-Up

  • Joint both edges of each strip: A clean, square edge is critical for tight glue lines
  • Dry-fit before gluing: Clamp all your strips together without glue first to check for gaps and alignment
  • Alternate growth rings: If using a single species, alternate the growth ring orientation on each strip to minimize cupping
  • Use cauls: Flat clamping cauls above and below the panel keep everything flat during glue-up
  • Glue in stages: For boards with many strips, consider gluing in two or three sub-panels, then joining them once cured
  • Use food-safe glue:Titebond III is the standard choice for cutting boards—it's waterproof and FDA-approved for indirect food contact

Edge Grain vs. End Grain vs. Face Grain

There are three orientations for cutting board construction, each with different characteristics:

  • Edge grain (this calculator): Strips glued with the edge facing up. Durable, attractive, and moderately knife-friendly. The most popular choice for everyday cutting boards.
  • End grain: Wood blocks glued with the end grain facing up. The gentlest on knives because the blade slides between wood fibers instead of cutting across them. More complex to build and uses more material.
  • Face grain: A single wide board (or boards glued face-to-face) with the widest face up. Simplest to make but shows knife marks more readily and is hardest on blade edges.
