Stop uploading blurry 1200×300 Etsy banners. Design at Etsy’s full 3360×840 (4:1) retina specification with AI product cutouts and editorial fonts.
Many tools default to 1200 × 300 px, which looks pixelated on modern MacBooks and iPhones. Designing at 3360 × 840 px gives Etsy 2.8x more pixel density.
