Aspect ratio and number of images
Pick the right shape for where your image will be used, and decide how many variants to create.

Two settings in the studio shape every result: the aspect ratio and the number of images.
Aspect ratio
The aspect ratio is the shape of the image, written as width:height. Pick it before you create, because it changes the composition, not just the crop.
| Ratio | Shape | Good for |
|---|---|---|
| 1:1 | Square | Profile pictures, product tiles, feed posts |
| 4:5 | Tall rectangle | Instagram feed posts |
| 3:4 | Tall rectangle | Posters, marketplace product photos |
| 2:3 | Portrait | Portraits, book covers, Pinterest |
| 9:16 | Full phone screen | Stories, Reels, TikTok, phone wallpapers |
| 4:3 | Wide rectangle | Presentations, interiors |
| 3:2 | Classic photo | Landscapes, blog images |
| 16:9 | Widescreen | YouTube thumbnails, banners, desktop wallpapers |
Tips
- Portraits look best in 2:3 or 4:5. A square often crops the shoulders awkwardly.
- Landscapes and scenes need room: use 16:9 or 3:2.
- Text and posters read better in a tall format like 3:4.
Number of images
You can create 1 to 4 images at once. The price multiplies with the number.
| Images | Nano Banana 2 (20 each) | Nano Banana Pro (35 each) |
|---|---|---|
| 1 | 20 credits | 35 credits |
| 2 | 40 credits | 70 credits |
| 4 | 80 credits | 140 credits |
The total is always shown on the button before you create.
When to create more than one
- Exploring a new idea: create 3 or 4 and pick the best.
- Refining a known prompt: 1 is often enough.
- Final hero image: 2 to 4 on a better model, then choose.
Each image in a batch comes out a little different. See How AI image generation works for why.
Note
If some images in a batch fail, only those are refunded. You keep and pay for the ones that worked.
