The most common sizes are 90 × 54 mm (Sri Lanka, India and much of Asia), 85 × 55 mm (Europe) and 3.5 × 2 inches (USA and Canada). Choose the size your printer uses; the design adjusts automatically.
How do I print the cards myself?
Download the print sheet. It has 10 cards on each A4 page with cut marks, and the backs on the next page. Print on thick card (250 to 350 g/m²) at “Actual size”. For two-sided cards, print double-sided and flip on the long edge, then cut along the marks.
Can I send the design to a print shop?
Yes. Download the single-card PDF: it's the exact card size, with the front on page 1 and the back on page 2, and the text stays sharp at any size.
What does the QR code do?
Scanning it with a phone camera either opens your website or saves your contact details (a vCard) straight into the phone's contacts, so nobody has to type your number.
