Etsy banner size: big and mini shop banner dimensions

Etsy recommends 1600×400 pixels for a big shop banner (1200×300 minimum) and 1600×213 for a mini shop banner (1200×160 minimum). For the shop logo it recommends 500×500, and for the profile photo 400×400. Both banners are wider than the 3:1 limit of ChatGPT Image 2.5's exact sizes, so on Sume generate the big banner at 4:1 (the mini banner at 8:1) with Nano Banana 2, then resize it to Etsy's pixels in an image editor.

Etsy's numbers are quoted from its Help page Requirements and Best Practices for Images in Your Etsy Shop, and Sume facts from the Image API docs and the model catalog, all read on 2026-09-28.

What size should an Etsy banner be?

The big banner is a 4:1 strip, and the mini banner is about 7.5:1, a much thinner one. Carousel and collage banners are only for sellers subscribed to Etsy Plus; a collage needs at least 600×300 for two images, 400×300 for three and 300×300 for four.

How do I make an Etsy banner with AI?

Ask POST /v1/images for a 4:1 image from Nano Banana 2 (google/nano-banana-2), with a resolution tier of 512, 1K, 2K or 4K, and leave plain space on one side for your shop name. The docs don't give each tier's pixel size, so check that the file is at least 1600 pixels wide, and ask for a higher tier if it isn't. AI banner generator for wide sizes covers the other wide shapes and where each model's rate is listed.

• Set the shop name in your editor rather than in the prompt, so every letter and the font are exactly yours.
• usage.cost in the response is the amount billed, and results are Sume-hosted, signed URLs in data[].url, so download the banner you keep.

curl -X POST "https://api.sume.com/v1/images" \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "google/nano-banana-2",
    "prompt": "Etsy shop banner for a handmade ceramics shop: an abstract speckled glaze texture in cream and soft blue, calm light, the left half plain, no text",
    "aspect_ratio": "4:1",
    "resolution": "2K",
    "output_format": "jpeg"
  }'

How do I resize the banner to Etsy's size?

Scale the 4:1 file down to 1600×400 in an image editor. For the mini banner, start from an 8:1 image at least 1,704 pixels wide, trim the sides to keep about 94% of its width, then scale it to 1600×213. Etsy notes that shrinking an image won't lower its resolution, but enlarging one can make it pixelated, which is why the file should start at least 1600 pixels wide.

Etsy compresses uploaded images, so a banner may look less sharp on the site than in your editor. It also converts images to the sRGB color profile; if the colors look wrong on Etsy, convert the file to sRGB before uploading.

What file types does Etsy take for banners and logos?

• Etsy supports .jpg, .gif, .png, .svg and .heic only.
• Animated GIFs and transparent PNGs aren't supported; transparent parts show up black. Flatten a cutout onto a background color first.
• Nano Banana 2's catalog lists png, jpeg and webp output today. Ask for jpeg or png, since WebP isn't on Etsy's list.
