Cut lists that actually add up.

Built against the complaints, not the feature list.

Every point below comes from a specific, repeated failure in this category. Some of them cost people real money in wasted material.

• Every part is placed or reported

  If a part cannot fit, Sawgrid blocks and names it, with its size and the stock item it was measured against. It will not hand you a plan that is quietly missing a piece.

• The kerf is real

  The blade eats material out of the free area beside a part. It is never added to the part size, and no kerf is charged at an outside edge of a panel, because there is no cut there.

• Grain direction per part

  Three valued on every single part: free to rotate, forced lengthwise, forced crosswise. Inherited from the material, overridable anywhere. The stock panel carries its own grain axis.

• Several materials, one run

  A carcass job mixes 19 mm plywood, a 6 mm back panel and solid timber. Sawgrid solves all of them at once, with a separate plan per material and one consolidated shopping list.

• Your offcuts are stock

  Leftovers carry a size, a quantity and a priority. Give them a lower priority number than fresh sheets and the optimizer will use up the rack before it cuts into a new panel.

• No slivers pretending to be offcuts

  A leftover strip narrower than your minimum is counted as waste, not as stock. Nobody can hold a 1.5 mm ribbon against a fence, so Sawgrid does not pretend you can.

• One field, any unit

  No unit switch to forget. The same box understands 720, 18mm, 1,8 cm, 3/4", 0.75in, 24 1/2 and 2' 6 3/4.

• A PDF that actually prints

  One page per sheet, drawn to scale and dimensioned, plus the cut list in cutting order and the area balance. Straight through the normal share sheet, so it prints, AirDrops and saves to Files.

• Offline, on device, no account

  The optimizer, the drawings and the export all run on the device in your hand. There is no login screen, no sync, and nothing to fail in a basement workshop with no signal.

Three steps, then you cut.

No wizard, no gratis run to burn by mistyping a number, no paywall between you and the result you already typed in.

1. Type the parts

   Name, width, length, quantity, grain. Paste a room full of panels in one go, or add them one at a time. Every field takes any unit you feel like typing.

2. Describe your stock

   Full sheets, half sheets and the offcut rack, each with a quantity and a priority. Set the kerf of your blade and the trim your supplier leaves on the edge.

3. Solve and print

   Plans per material, a cut list in the order you will actually cut, a shopping list, and a balance that closes. Then a PDF for the wall next to the saw.

What is under the lid.

Not because you have to care, but because the plans are only as trustworthy as the arithmetic behind them.

• 108

  Candidate plans per run

  Six split rules times three placement rules times six sort orders. No single heuristic wins consistently, the winner changes with every job, so Sawgrid runs them all and keeps the best one.

• 0.1 mm

  Integer arithmetic, no floats

  Every length in the app is a whole number of tenths of a millimeter. One inch is exactly 254 of them. Same discipline that stores money as integer cents, for the same reason: drift is not acceptable.

• 1 : 1

  Deterministic by construction

  Solve the same project twice and you get identical plans. The optional refinement pass is seeded from a fixed constant, never from the clock, so a plan you printed yesterday is the plan you get today.

• < 0.3 s

  Fast enough to keep tweaking

  A few hundred parts solve while your thumb is still on the button. Change one dimension, resolve, compare. That is the loop the category has been missing.

What is free, and what Pro costs.

Every competing app in this category meters the calculating. Sawgrid does not, and it says plainly where the line is instead of finding out at the paywall.

• Free, with no counter running

  Calculating is free and stays free: as many parts and panels as a job has, as many recalculations as you like, all 108 strategies on every run, and the full cutting plan on screen with dimensions, part names and the area balance. Nothing is metered, and no attempt is burned by a typo.

  The free plan works on one project at a time, with one material, at a fixed 3.0 mm saw kerf.

• Pro is the workflow around the plan

  The multi page PDF, the label sheet and the CSV cut list. Your own blade kerf instead of the fixed one. A grain rule per part. Several materials in one project. More than one project at a time. Saw table mode. The offcut inventory that carries across projects. The slower, more thorough optimisation pass.

  Pro is a subscription or a one time purchase. The lifetime price is the same as one year — pay for a year, or pay once and be done.
