How Many Gang Sheets Do I Need? An Order Worksheet

Count the transfers required by the order before choosing a gang sheet size. Fifty shirts do not always mean fifty graphics: front and back decoration, different sizes and approved spare copies all change the quantity. This worksheet turns an order list into a sheet requirement without treating empty film area as usable production.

1. Build a transfer list

Give every design and size combination its own line. Record artwork version, printed width and height, garment quantity and approved spares. A small chest logo and a large back graphic are separate items even when they use the same source file. Confirm dimensions at final print size; the blank canvas around a PNG is not the visible artwork.

For each line: required copies = garments × copies per garment + planned spares. Two placements require two transfer counts. Choose spares deliberately for sampling and production risk; there is no universal percentage suitable for every job.

2. Calculate a simple grid capacity

Ask the printer for the actual printable width, usable length, edge margins and minimum spacing. For identical rectangular designs in one orientation, let W and H be the usable dimensions, w and h the design dimensions, and g the gap:

Columns = floor((W + g) ÷ (w + g)); rows = floor((H + g) ÷ (h + g)); copies per sheet = columns × rows.

Floor means round down. The extra gap in the numerator accounts for having one fewer gap than designs. This is a grid estimate, not an optimized nesting result. Rotation or irregular shapes may change the arrangement; check the printer's actual builder before ordering.

3. Worked example: 50 shirts, one front graphic

Assume 50 garments, one 10 × 10 inch graphic each and two planned spare transfers: 52 copies. All dimensions and prices below are illustrative, not supplier specifications or quotations.

The example reserves half an inch at each outer edge and a quarter-inch gap between designs. Thirteen short sheets provide exactly 52 spaces; six long sheets provide 60. Eight unused spaces are capacity, not eight extra transfers unless you put artwork there and order it.

4. Compare the whole order cost

If a short sheet hypothetically costs $18 and a long sheet $38, the film orders cost $234 and $228 respectively. Add shipping, setup, cutting time and any minimum order terms before choosing. The cheapest square inch need not produce the cheapest completed job.

For mixed designs, create the full layout with exact copy counts and inspect the exported proof. Do not add separate maximum capacities: two designs cannot occupy the same space. Check every row against the order list, including mirrored versions only where the supplier requires them.

5. Release checklist

• Confirm each design, version, size and placement.
• Reconcile required copies and spares.
• Verify margins and gaps with the printer.
• Check final layout counts and export dimensions.
• Save the approved proof with the order.
