Sticker Labels Per Sheet Calculator
On A4 (21 × 29.7 cm) a 0.5 cm margin all round leaves 20 × 28.7 cm to work with. Setting 5 × 3 cm labels 0.2 cm apart, across you get (20 + 0.2) ÷ (5 + 0.2) = 3.88 → 3, and down (28.7 + 0.2) ÷ (3 + 0.2) = 9.03 → 9, so 27 labels. One gap is added before dividing because three labels have only two gaps between them. Turn the labels 90° and it becomes 6 across by 5 down — 30 labels, three more. Count both ways before you lay the sheet out.

Formula
Per row = ⌊(Sheet width − 2 × Printer margin + Gap between labels) ÷ (Label width + Gap between labels)⌋, Rows down the sheet = ⌊(Sheet length − 2 × Printer margin + Gap between labels) ÷ (Label height + Gap between labels)⌋, Labels per sheet = Per row × Rows down the sheet
Real printer margins differ by model and are wider on the feed edge, so a margin of zero silently crops the last row — test-print before committing. If a cutting machine is doing the trimming, keep at least 0.2 cm of gap for the blade path and add the bleed to the label size, since the cut line sits slightly outside the label.
What to enter
| Input | Default | Accepted range |
|---|---|---|
| Sheet width (cm)The paper width you print on — 21 cm for A4. | 21 | 1 and up |
| Sheet length (cm)The paper length you print on — 29.7 cm for A4. | 29.7 | 1 and up |
| Label width (cm)One label across, measured out to the cut line. | 5 | 0.1 and up |
| Label height (cm)One label down, measured out to the cut line. | 3 | 0.1 and up |
| Printer margin (cm)The border the printer cannot reach; it differs by model, so test-print it. | 0.5 | 0 and up |
| Gap between labels (cm)The space left between labels, where the blade or the scissors travel. | 0.2 | 0 and up |

Common mistakes
Real printer margins differ by model and are wider on the feed edge, so a margin of zero silently crops the last row — test-print before committing. If a cutting machine is doing the trimming, keep at least 0.2 cm of gap for the blade path and add the bleed to the label size, since the cut line sits slightly outside the label.

Frequently asked questions
Q. How is Sticker Labels Per Sheet Calculator calculated?
Per row = ⌊(Sheet width − 2 × Printer margin + Gap between labels) ÷ (Label width + Gap between labels)⌋, Rows down the sheet = ⌊(Sheet length − 2 × Printer margin + Gap between labels) ÷ (Label height + Gap between labels)⌋, Labels per sheet = Per row × Rows down the sheet — On A4 (21 × 29.7 cm) a 0.5 cm margin all round leaves 20 × 28.7 cm to work with. Setting 5 × 3 cm labels 0.2 cm apart, across you get (20 + 0.2) ÷ (5 + 0.2) = 3.88 → 3, and down (28.7 + 0.2) ÷ (3 + 0.2) = 9.03 → 9, so 27 labels. One gap is added before dividing because three labels have only two gaps between them. Turn the labels 90° and it becomes 6 across by 5 down — 30 labels, three more. Count both ways before you lay the sheet out.
Q. Can you walk through an example?
With Sheet width 21cm, Sheet length 29.7cm, Label width 5cm, Label height 3cm, Printer margin 0.5cm, Gap between labels 0.2cm, the answer is Labels per sheet 27.
Q. What do I need to enter?
Enter Sheet width, Sheet length, Label width, Label height, Printer margin, Gap between labels. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Sheet width (cm) moves the answer to Sheet width (cm) 10.5 → Labels per sheet 9 and Sheet width (cm) 42 → Labels per sheet 63. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Real printer margins differ by model and are wider on the feed edge, so a margin of zero silently crops the last row — test-print before committing. If a cutting machine is doing the trimming, keep at least 0.2 cm of gap for the blade path and add the bleed to the label size, since the cut line sits slightly outside the label.
