Cover Checker
Spine size and thumbnail test for your finished book cover. Check it before you publish.
Paperback wrap size
IngramSpark gives the exact spine in its free template generator. Type it here and the wrap size is worked out for you.
Dashed red lines mark the fold between back, spine and front.
All results are estimates. Always check them against your printer's own template before you export.
Thumbnail tester
Check at the smallest size: can you still read the title and spot the genre? If not, enlarge the title or simplify the background. Your image stays on your device.
3D mockup
Thickness and shape follow the page count and trim size from the Spine tab. Screenshot it for your listing or social posts. Use the front cover only, without spine or back.
