Mirror cutting optimiser: mirrors laid out on the sheet

Type or paste your sizes and get the plan with the least waste. In your browser, no sign-up.
What it does and how it is worked out

Lay out a mirror order on the sheet, free and in your browser. The list below is an example, three bathroom mirrors of 1000 × 800, two wardrobe door mirrors of 600 × 1600 and four small ones of 500 × 700 mm, so you see a result straight away: 1 DLF sheet of 3210 × 2250 and 79.2 % yield. Clear it and put in your own sizes.

Free, no sign-up, no email. Everything you type stays in this browser — your cutting list never reaches us.

Mirror is bought on sheets of its own and cut like glass, scored and snapped edge to edge: the same strips, the same trim and the same offcuts, kept apart from clear glass.

Trim and breakout
Edge trim is the damaged rim you cannot use — a few millimetres on a clean rack, more on a sheet that has travelled. Breakout width is the strip you lose between two pieces when you snap them apart; if you leave it at zero the answer will be optimistic and the cutter will disagree with you.
Glass price and type
Write the glass in your own words. It is only ever compared with itself, and it is what stops the rack offering you a 6 mm clear offcut for a 4 mm low-e order.
Offcut rack
The rack — offcuts you already own
Glass you have already paid for. This job is cut out of it before it buys a sheet — how it decides, and what it is worth.

Rotation
Rotation
Fix the orientation for anything directional: patterned glass, some laminated interlayers, and any coated product where the coating side and the drawing direction have to be kept. It costs yield — the page will tell you exactly how much.

Workshop templates, example sizes: Bathroom mirrors for ten flats · A gym wall, mirrors 2 m high · Wardrobe door mirrors. Other jobs: shower screens · windows · shop windows

Each row is one size: width, height and how many of them.
Sizes are finished glass, cut size. If you work to a tolerance, subtract it before you get here — this page does not guess it for you.

The plan is the shop-floor version of this: every piece labelled on the diagram, the cuts in the order the table makes them, and each offcut with its real size for the rack. It stays in your browser like everything else here.

Working out the cut is free and stays free. Pro holds 400 offcuts on the rack instead of 25, prints a label for every pane and keeps your saved jobs, for €29 once. What Pro adds →

What the software does in a glass shop

More than the nesting. What a workshop needs around a cutting list is here too, and none of it leaves this browser:

  • Each pane carries its own data. A reference, a shape (rectangle, circle or triangle) and the glass it is cut from; a list pasted from a spreadsheet keeps them, and the plan groups the panes by glass.
  • A rack of offcuts that knows where they are. Each offcut can have its place in the shop and a photo, and the next job is cut from the rack first.
  • The plan and the labels for the table. The cutting plan can carry your logo, and every pane can get a label with a QR code.
  • A log of what was cut. Today's jobs stay listed, to print the plan or the labels again.

To see it on a real order, open the example job. With Pro the rack holds 400 offcuts instead of 25 and every pane gets a label.

The example of this page, worked out

The list the page opens with is an example of a mirror order, not a customer's order: 3 × 1000 × 800, 2 × 600 × 1600, 4 × 500 × 700 mm (quantity × width × height), on DLF sheets of 3210 × 2250 mm with 10 mm edge trim a side and 4 mm breakout, panes allowed to turn. The figures are the optimiser's own, worked out by the same code as the tool above.

Questions people ask

How many glass sheets does this mirror order take?
The example on this page, 3 × 1000 × 800, 2 × 600 × 1600, 4 × 500 × 700 mm (quantity × width × height), fits on 1 DLF sheet of 3210 × 2250 mm with 10 mm edge trim and 4 mm breakout, at 79.2 % yield, and 4 offcuts go back on the rack. Put in your own sizes and the page works out yours.
Which side is a mirror cut on?
On the glass face, never on the coated back.
