What sizes does DALL·E 2 support?

DALL·E 2 generates square images at 256×256, 512×512 or 1024×1024 pixels. Unlike DALL·E 3, it does not offer landscape or portrait aspect ratios, so all outputs are square.

How much does each DALL·E 2 size cost?

At OpenAI's published rates, DALL·E 2 costs roughly $0.016 per 256×256 image, $0.018 per 512×512 image and $0.02 per 1024×1024 image. The size choice barely changes the price, so picking the largest you need is usually the better value.

Should I just always pick 1024×1024?

Often yes — at only a fraction of a cent more, 1024×1024 gives you the most resolution to crop, downscale or upscale from. Use smaller sizes only when you specifically need many tiny images cheaply and never plan to enlarge them.

Should I use DALL·E 2 or DALL·E 3?

DALL·E 3 follows prompts more faithfully and produces sharper, more coherent images, but costs more. DALL·E 2 is cheaper and supports editing and variations workflows. For final, high-quality assets prefer DALL·E 3; for cheap bulk drafts or variation experiments, DALL·E 2 can be fine.

DALL·E 2 Size Picker

DALL·E 2 size picker

DALL·E 2 offers three square sizes — 256×256, 512×512 and 1024×1024 — and the price difference between them is tiny. This picker shows the per-image cost, quality trade-offs and best use case for each, and gives you a batch total so you can choose with full information before generating.

How it works

The tool maps each size to its published per-image rate and a recommended use: 256×256 for tiny thumbnails or icon experiments, 512×512 for in-feed social content, and 1024×1024 for anything you might crop, print or upscale. Because the cost gap between the smallest and largest is only a fraction of a cent, the recommendation usually favours generating at the largest size you might ever need and downscaling afterwards. Enter an image count to see the full batch total.

Tips and notes

Default to 1024×1024. The extra resolution costs almost nothing and gives you room to crop and upscale.
DALL·E 2 is square-only. If you need landscape or portrait, use DALL·E 3 or crop afterwards.
Use small sizes only for true bulk. Hundreds of disposable thumbnails are the main case where 256×256 pays off.
