What is this free small business insert card maker for?
This free online tool puts multiple small business packaging cards onto one standard A4 or US Letter sheet. It automatically makes a front page and a matching back page for fast double-sided printing. You can use it for customer thank-you cards, package inserts, jewelry tags, care instruction cards, and promotional coupon notes.
Maximum cards per page
Fit up to 8–10 standard business cards, 12 mini square cards, or custom-sized inserts to save cardstock paper.
Front and back stay aligned
Both PDF pages use exact matching grid coordinates so your double-sided cards align back-to-back when cut.
Fast straight cutting
Set card spacing to 0 mm to slice entire batches rapidly with straight continuous edge cuts on a paper trimmer.

Frequently asked questions
Simple answers about card layouts, printing double-sided inserts, paper weight, and alignment.
How many insert cards fit on one US Letter or A4 sheet?
On standard US Letter or A4 paper, you can fit 8 to 10 standard business cards (3.5 × 2 inches), 12 mini square cards (2 × 2 inches), 6 medium square cards (2.5 × 2.5 inches), or 4 large postcard-size inserts (A6).
Can I enter my own custom card dimensions?
Yes. Select Custom Dimensions in the card preset options, and enter any width and height in millimeters. The layout engine will recalculate the best grid fit instantly.
How do I cut the cards quickly after printing?
Keep the card spacing set to 0 mm. This places the cards flush against each other so you can trim through the entire page with single straight cuts on a paper trimmer.
Why is the back side slightly shifted when printed?
Many home printers pull the second side of paper slightly off-center. Print a test sheet, measure the shift with a ruler, and enter a Back X or Back Y calibration value in millimeters.
What cardstock paper is recommended for packaging cards?
We recommend 65 lb to 110 lb (176 to 300 gsm) smooth matte white cardstock. Check your printer manual to ensure it supports your chosen paper thickness.
Are my logo and card files uploaded to a server?
No. Your files stay on your device. The calculations, previews, and PDF downloads are processed entirely inside your web browser.
