A plan may include both lists, and it’s tempting to treat them as two versions of the same thing. They serve different jobs. Understanding the difference can make preparation easier and help you ask a useful question when something doesn’t add up.

The shopping list starts with stock.

A shopping list names the boards, sheets, hardware and other materials you need to obtain. It should describe quantities and stock sizes clearly enough that you can compare them with the supplier’s products.

Some supplies may be separate from the main build materials. Look for that distinction rather than assuming a lumber subtotal includes finish, growing medium or every item you’ll use.

The cut list starts with parts.

A cut list names the pieces that go into the project: how many of each part to make and the finished dimensions of those parts. Part labels should carry through to the assembly drawings so you can see where a cut piece belongs.

Stock size and finished size are not always the same. Before marking a cut, check the plan’s units, stated section sizes and any notes about shaping or trimming.

A stock length does not divide itself.

How the cuts fit onto the stock matters. The saw removes material between pieces, and the actual board may need an end trimmed before you start. A board layout can help show the intended arrangement; use the plan’s stated cutting allowance rather than adding up finished lengths alone.

If you’re changing a stock length, a material or a project size, recheck the layout. Substitutions can affect more than the shopping quantity.

Read the two lists together.

  • Confirm the project size and units at the top of the plan.
  • Match the stock sections in the shopping list to the cut parts that use them.
  • Check part labels against the drawings before marking pieces.
  • Read any board layouts and cutting notes before making the first cut.
  • Ask about an unclear quantity or dimension before committing material.

Keep the lists where you can refer to them as you work. The shopping list gets materials to your workspace. The cut list helps turn those materials into the parts the assembly expects.

General planning guidance. Follow your chosen plan and tools’ instructions; ask about unclear dimensions or substitutions before cutting.
