What 21 labels per US Letter sheet means
A count of 21 per sheet does not fix the label size: the 3 sheets here use 2 sizes and 1 grid (3 × 7). Labels cover between 61 % and 95 % of the US Letter page; the rest is margin and gaps.
Always choose the template by the code printed on the box: two 21-up sheets with different sizes or margins need different templates, even though the count matches. The most common size at this count is 1 1/2″ × 2 5/6″ (2 sheets).
21-up sheets grouped by label size
| Label size | Columns × rows | Sheets | Example codes | Top / side margin | Coverage |
|---|---|---|---|---|---|
| 1 1/2″ × 2 5/6″ | 3 × 7 | 2 | SheetLabels SL552, OnlineLabels OL5350 | 1/4″ / 0″ | 95 % |
| 1 3/8″ × 2 1/2″ | 3 × 7 | 1 | OnlineLabels OL9830 | 1/2″ / 7/16″ | 61 % |
How many 21-up sheets you need
Sheets needed for a run of labels at 21 per sheet, starting on a fresh sheet, and when the first 7 positions of a used sheet are already gone (start at label 8).
| Labels | Sheets (fresh sheet) | Sheets (start at label 8) | Blank labels left |
|---|---|---|---|
| 50 | 3 | 3 | 13 |
| 100 | 5 | 6 | 5 |
| 250 | 12 | 13 | 2 |
| 500 | 24 | 25 | 4 |
| 1000 | 48 | 48 | 8 |
Which 21-up sheet to pick
SheetLabels SL552 is the default here because it shares its exact layout with 1 other sheet on this list, so its template prints on those too. Its labels are 2 5/6″ (72 mm) by 1 1/2″ (38.1 mm).
1 1/2″ × 2 5/6″ is already the largest size at this count; the smallest are 1 3/8″ × 2 1/2″ on OnlineLabels OL9830.

Frequently asked questions
What size are the labels on 21-up sheets?
It depends on the sheet: 1 1/2″ × 2 5/6″ (SheetLabels SL552) and 1 3/8″ × 2 1/2″ (OnlineLabels OL9830).
How many sheets do I need for 500 labels at 21 per sheet?
24 sheets (4 labels left blank). For 100 labels: 5 sheets.
Is every 21-up template the same?
No. There are 2 different layouts at this count; label sizes and margins differ, so pick the template by the code on your box.
How do I print 21 labels per sheet correctly?
Download the PDF from the designer and print on US Letter paper at 100 % (“Actual size”), without “fit to page”. Print one test page on plain paper and hold it against a label sheet first.
