Business Cards Per Sheet Calculator

Find how many business cards fit on a sheet and how many sheets you need for 100 cards.

How it is calculated

All four sizes are entered in centimetres. The tool counts a simple grid in two layouts. Layout A puts the card upright: ⌊sheet width ÷ card width⌋ × ⌊sheet height ÷ card height⌋. Layout B turns every card 90 degrees: ⌊sheet width ÷ card height⌋ × ⌊sheet height ÷ card width⌋. The larger count is reported as cards per sheet, and sheets for 100 cards is ceil(100 ÷ cards). Every card in a sheet has the same orientation; mixed layouts are not tried. Margins, gutters between cards, bleed and printer non-printable edges are not subtracted, so enter the usable sheet area. If not even one card fits, there is no result.

Worked example

A US Letter sheet is 21.59 × 27.94 cm, and the card is 8.9 × 5.1 cm. Upright: ⌊21.59 ÷ 8.9⌋ = 2 and ⌊27.94 ÷ 5.1⌋ = 5, so 2 × 5 = 10. Rotated: ⌊21.59 ÷ 5.1⌋ = 4 and ⌊27.94 ÷ 8.9⌋ = 3, so 4 × 3 = 12. The rotated layout wins. Result: 12 cards per sheet. For 100 cards: 100 ÷ 12 = 8.33, rounded up to 9 sheets.

Common mistakes

  • Entering sizes in inches or millimetres. The fields are in centimetres, so a 3.5 in card must be typed as 8.9 and an 85 mm card as 8.5.
  • Forgetting that printers cannot print to the paper edge. Enter the printable area, not the full sheet, or the count may be one row or column too high.
  • Ignoring the gap between cards. With no spacing or bleed in the tool, a count that fits exactly with zero gap will not fit once crop marks and bleed are added.
  • Expecting the sheet count to be a final order. It covers 100 cards only, and any spoilage for test prints and misaligned cuts is extra.
  • Mixing portrait and landscape cards on one sheet. The tool uses one orientation per sheet, so a mixed layout may fit more than it reports.

About this calculator

Fitting business cards onto a print sheet is a rectangle-packing problem: for a sheet of width W and height H and a card of width w and height h, the count in one orientation is ⌊W/w⌋ × ⌊H/h⌋, and since rotating the cards 90° often fits more (or fewer) onto the same sheet, the calculation checks both orientations and keeps whichever packs more cards without waste.

This is exactly the layout logic print shops and design software use when imposing multiple business cards (commonly 3.5" × 2" or 85mm × 55mm) onto standard sheet sizes like US Letter or A4 before cutting, since printing the wrong grid wastes paper, ink, and cutting time on a job that's often produced in bulk.

Small business owners printing their own cards at home, graphic designers setting up print-ready templates, and print shop operators quoting jobs by the sheet all use this calculation to know exactly how many sheets a run of 100, 250, or 500 cards will require.

    The grid assumes the whole sheet is printable and the cards touch with no gutter. On a 21 by 29.7 cm sheet, 8.9 by 5.1 cm cards give 12 per sheet and 9 sheets for 100 cards. Shrinking the sheet to 20 by 28.7 cm for printer margins drops that to 10 per sheet and 10 sheets. Bleed counts too, so put the sizes with bleed in the card fields. What sheet sizes do you print on?
