WebNovel cover size guide
Everything you need to export a WebNovel cover that looks sharp everywhere readers will see it — homepage grids, search results, bestseller ranking rows, and the mobile app.
The short answer
WebNovel displays every cover at a 3 : 4 aspect ratio. Upload your art at 1200 × 1600 px or larger (the absolute minimum is around600 × 800 px) as JPG, PNG, or WebP, and design so the title stays readable when the whole thing is squeezed into a 40-pixel-tall ranking row.
Every placement, at a glance
| Placement | Typical display size | What to check |
|---|---|---|
| Source upload | 3 : 4 ratio · min 600 × 800 px · 1200 × 1600 px recommended | Sharpness headroom for every smaller placement |
| Website homepage & popular grids | ≈ 256 px wide tiles | Title readable at a glance |
| Search results & library lists | ≈ 72 px tall thumbnails | Art stays recognizable, colors stay distinct |
| Bestseller ranking rows | ≈ 40 px tall | Silhouette and palette still stand out |
| Mobile app details page | Full-width card at ~3 : 4 | Key art survives overlays and gradients |
Why the ratio matters
If your file is wider or taller than 3 : 4, WebNovel crops or pads it to fit — and you do not get to choose what survives. A 1 : 1 square loses its sides; a tall 2 : 3 poster loses its top. Export at exactly 3 : 4 and what you design is what readers see.
Export settings that survive compression
- JPG at 85–90% quality for painted or photographic art — the best size-to-sharpness trade-off after platform compression.
- PNG for flat colors, crisp typography, or heavy gradients banding in JPG.
- sRGB color profile — wide-gamut profiles shift colors on most phones.
- Keep the final file under 10 MB; there is no benefit to more.
- Avoid re-saving an already-compressed JPG repeatedly — artifacts compound.
Designing for the smallest thumbnail
Most readers first meet your novel in a list of forty covers, each about 40 pixels tall. The covers that get clicked are the ones that still work there:
- One clear focal subject — faces and single objects beat busy scenes.
- High contrast between the title and the art behind it.
- A title large enough that it reads at thumbnail size — if you must squint at full resolution, it is too small.
- No thin lines or fine detail — they vanish on downscale.
- A distinct color palette so your cover stands apart in a ranked list.
