300 DPI · Print-ready · White background · Accepted by IngramSpark, KDP & B&N Press

📐 Where to place it

Bottom-right corner of your back cover. IngramSpark requires at least 0.25" clear space around the barcode.

📏 Minimum size

At least 1.5" wide × 1.02" tall. Larger is fine. Never scale below 80% of the original — barcodes fail to scan when too small.

🎨 Color rules

Black bars on white background only. Never print on a colored or gradient background — scanners will fail.

🔢 ISBN-13 vs ISBN-10

All modern books use ISBN-13 (starts with 978 or 979). ISBN-10 is obsolete — use your 13-digit number.
