How to Make a Cut List: Step-by-Step Woodworking Guide

A cut list is how a project moves from drawings to lumber yard to shop floor without chaos. It is a complete inventory of every part you need to cut, with exact dimensions, materials, and grain requirements — written down before you touch a saw. Without one, you are improvising at the worst possible time: when expensive wood is on the table.

This guide walks through the full process of making a cut list, from reading your plans to walking into the shop with a complete cutting strategy in hand.

Why You Need a Cut List

The argument against making a cut list is always the same: "I know this project well enough to just cut from the plans." This works occasionally on simple builds. It fails consistently on anything complex — and the failures are expensive.

Here is what happens without a cut list:

• You cut a part to the wrong length because you grabbed the wrong dimension off the drawing
• You run out of material because you did not account for kerf losses across 12 rip cuts
• You cut three panels with grain running the wrong direction and only notice at assembly
• You buy an extra sheet of plywood on spec and have no use for it

A cut list catches all of these problems before they happen. It forces you to work through the entire project mentally before committing any material. That up-front thinking is where the real savings come from.

Step 1: List All Parts from Your Plans

Start with finalized, dimensioned drawings. A cut list built from a rough sketch will contain rough errors. If your plans are not locked, finish them first.

Work through the project systematically — usually carcase first, then internal parts, then face frames or trim. For a cabinet, you might go: sides, top, bottom, back, fixed shelves, face frame stiles, face frame rails, doors, drawer boxes, drawer fronts. For a workbench: top, legs, stretchers, shelf, aprons.

List every distinct part. Do not skip small pieces. The block that fills a gap or the cleat that supports a shelf can cause real problems if it is missing from your shopping math.

For each part, record:

Group identical parts into a single row with a quantity. Two drawer bottoms with the same dimensions from the same material are one row, quantity 2 — not two separate rows.

Step 2: Specify Exact Dimensions

Every dimension on your cut list should be the finished dimension — the size the part will be when it goes into the assembly. Not rough-cut size. Not nominal lumber size. Finished size.

Finished vs. Rough Dimensions

If you are buying S4S (surfaced four sides) lumber and cutting directly to size, your cut list dimensions are your cutting dimensions. If you are milling rough lumber through a jointer and planer, your cut list carries the final milled dimensions. The rough-cutting oversize — leaving parts an inch long and a quarter-inch fat — is a shop habit, not a cut list entry.

Nominal vs. Actual Sizes

Never use nominal lumber designations in a cut list. A 1×4 is 3/4" thick and 3-1/2" wide. A 2×4 is 1-1/2" thick and 3-1/2" wide. A 3/4" sheet of plywood is often actually 23/32" (0.719").

Measure your actual stock and use those numbers. Especially for plywood: the nominal thickness marked on the sheet may not match what your caliper reads, and a 1/32" discrepancy multiplies across a cabinet full of dados and rabbets.

Checking Your Dimensions

Before finalizing any row, ask: does this dimension match the drawing? Then ask: does this dimension make sense in the assembly — is the part actually going to fit?

Cross-check critical fits: a shelf that sits in a dado needs to match the dado width. A drawer box that slides into an opening needs to be sized to leave the right clearance. Catch these on paper, not in the shop.

Step 3: Choose Materials for Each Part

Specify material precisely. "Oak" is not precise enough. "Red oak, 4/4 S2S" or "white oak, 5/4 rough" tells you what to buy. For sheet goods: "3/4 Baltic birch" or "1/2 cabinet-grade maple plywood" or "3/4 MDF."

Why Material Specification Matters

Different materials have different actual thicknesses even at the same nominal size. Sheet goods from different suppliers vary. Specifying material at this step forces you to make those decisions now, which means your dimensions are accurate and your shopping list is correct.

For multi-material projects — common in cabinet work where the carcase is plywood and the face frame is solid wood — keeping material clear in the cut list prevents the wrong piece going to the wrong process. You do not want to send a plywood panel through the drum sander.

Grouping by Material

Sort your cut list by material type before you head to the shop. All the 3/4" plywood parts together, all the 4/4 hard maple together, all the 1/4" ply together. This makes layout optimization possible and shopping fast.

Step 4: Account for Kerf and Saw Blade Waste

Kerf is the material destroyed by the saw blade on every cut — typically 1/8" for a standard 10" table saw blade. On a single cut it is negligible. Across a full layout it adds up fast.

The Kerf Math

If you are ripping a 48"-wide sheet into 6"-wide parts, your first instinct might be that 8 parts fit (8 × 6" = 48"). In reality, you need 7 cuts to produce 8 parts from a single sheet, and each cut removes 1/8" of kerf. That is 7/8" of lost material. You actually get just over 47" of usable width — enough for 7 full parts and a 5-1/8" scrap.

The formula for how many crosscut parts fit on a board:

parts = floor((board_length + kerf) / (part_length + kerf))

The + kerf in the numerator accounts for the fact that the last part does not need a trailing cut.

Applying Kerf in Practice

For manual cut lists, the safest approach is to add 1/8" between every part when calculating layout. Most woodworkers add a small safety margin on top of that — treating kerf as 3/16" — to account for blade wobble, slight misalignment, and the fact that real lumber has occasional defects that require a small sacrifice cut.

If you are using a cut list optimizer, kerf is handled automatically. You enter your blade's kerf width once, and every layout calculation across every sheet and board accounts for it.

Step 5: Optimize Layout on Stock

With all parts listed and dimensioned, you need to figure out how they arrange on your available stock. This is layout optimization, and it is where you discover your actual material requirements.

Manual Layout

For solid wood boards, draw the board dimensions on graph paper and sketch your parts in. Pay attention to grain direction — parts with grain running lengthwise must be oriented with their long axis along the board. Mark defects in your stock (knots, checks, sapwood) and route parts around them.

For sheet goods, this is essentially a rectangle packing problem. Lay out your parts on a 4×8 grid and minimize waste. Common strategies:

• Strip ripping first: Rip the sheet into full-length strips at your part widths, then crosscut each strip into part lengths. This is efficient on the table saw and wastes less material than one-at-a-time cutting.
• Large parts first: Place the largest parts first, then fill in smaller pieces around them.
• Keep grain consistent: All face grain on sheet goods runs the same direction within a part unless you have a specific reason to rotate.

Using a Cut List Optimizer

For anything beyond a simple project, software optimization beats manual layout significantly. A cut list optimizer applies constraint-based algorithms to pack parts efficiently while respecting grain direction, minimizing kerf loss, and balancing across multiple sheets.

The result is a concrete cutting diagram: this strip from sheet 1, this strip from sheet 2, with the exact cut sequence. You see your actual sheet and board count before you buy anything.

Step 6: Export and Head to the Shop

Before you leave for the lumber yard, your cut list should give you:

• A complete part list with all dimensions
• A material list — how many sheets of each panel product, how many board-feet of each lumber species, organized by thickness and width
• A cutting diagram for sheet goods showing which parts come from which sheet
• A part sequence for solid wood boards showing the cut order

In the shop, use the cut list as a checklist. Mark each part as it is cut. For solid wood parts, mark the face side and grain direction on the part itself — a pencil arrow indicating grain direction takes two seconds and prevents a frustrating orientation mistake at assembly.

Stack parts in organized groups by assembly stage. Carcase parts together. Face frame parts together. Drawer parts together. Working through organized groups keeps the build efficient and surfaces missing pieces before you need them.

Pro Tips for Better Cut Lists

Oversize Tenon and Mortise Parts

If you are cutting mortise-and-tenon joinery, add tenon length to the cut list dimension. A rail with 1" tenons on each end needs to be cut 2" longer than its finished visible length. Many woodworkers add this directly to the cut list as the cutting dimension and note the tenon length in the Notes column.

Similarly, legs that will be cut to final length after mortising are often listed at their rough length with a note to trim after joinery.

Mark Grain Direction on Every Solid Wood Part

As you cut parts from solid wood boards, mark the grain direction with a pencil arrow on the face side. This takes seconds and prevents the mistake of orienting a part the wrong way during assembly — a mistake that is sometimes irreversible. Grain direction matters structurally for parts under load and visually for all face pieces.

Group by Material for Efficient Cutting

Once you have a complete cut list, reorder the rows so all parts from the same material are together. Cut all your 3/4" plywood parts in one session. Cut all your 4/4 maple in another. Switching between materials mid-session is inefficient and increases the chance of using the wrong stock.

Leave Assembly Fitting Parts Slightly Fat

Parts that will be fit to an existing opening — drawer boxes, door frames, fill pieces — should be cut slightly wider or longer than the nominal dimension and trimmed to fit during assembly. This is not about sloppy planning; it is acknowledging that real assemblies have small cumulative errors that exact-dimension parts sometimes cannot accommodate. Note these parts in your cut list as "trim to fit" with their nominal target.
