How much DTF film do you need, and does rotation save any?
Under the assumptions below (calculated 2026-10-23), 200 prints of 25×30 cm on a 60 cm roll need 30.695 m upright or 51.195 m rotated. Allowing rotation selects 30.695 m. Rotation does not always save film.
Fix spacing, margins and waste first
All dimensions here are illustrative assumptions: roll width 60 cm; left/right margins 1/1 cm; horizontal and vertical gap 0.5 cm; leading/trailing allowance 10/10 cm per run. Each example delivers 200 prints with 0% waste (the tool default is 5%). Shared settings other than quantity and waste use the tool defaults, not an equipment standard.
Upright places the first dimension across the roll. The rotated column forces width and height to swap. Automatic selection is the tool's “allow rotation” setting: it chooses the shorter whole-batch orientation, without mixing orientations.
Rotation helps some sizes, not others
| Size (cm) | Across (upright / rotated) | Upright (m) | Rotated (m) | Automatic (m) | Auto saving (m / %) |
|---|---|---|---|---|---|
| 25×30 | 2 / 1 | 30.695 | 51.195 | 30.695 | 0.000 (0.0%) |
| 30×25 | 1 / 2 | 51.195 | 30.695 | 30.695 | 20.500 (40.0%) |
| 20×28 | 2 / 2 | 28.695 | 20.695 | 20.695 | 8.000 (27.9%) |
| 10×15 | 5 / 3 | 6.395 | 7.230 | 6.395 | 0.000 (0.0%) |
Work through why rotation can use more film
In the first example, usable width = 60 − 1 − 1 = 58 cm. Prints across = floor((usable width + gap) / (design width + gap)). Upright fits 2 across and needs 100 rows; rotated fits 1 across and needs 200 rows.
Length = leading allowance + rows × design height + (rows − 1) × gap + trailing allowance. Upright gives (10 + 100 × 30 + 99 × 0.5 + 10) cm = 30.695 m.
Total artwork area divided by roll width misses partial rows, side margins and cutting gaps. Add an allowance for your process and the supplier's selling unit; this table does not round continuous lengths up to whole meters.
