Understanding image size and DPI requirements

When applying to calls, you may see image size requirements listed on the upload page. Here's what they mean and how to make sure your images meet them.

What the requirements mean

Calls list requirements in pixels — for example, "Minimum 1920px (long side)." This means the longest side of your image (either width or height) must be at least 1920 pixels.

Pixels are the only thing that matters. EntryThingy checks the pixel dimensions of your image, not the DPI.

What about DPI?

DPI (dots per inch) only matters when printing. It has no effect on how your image looks on a screen or how EntryThingy evaluates your upload.

A 2000×1500 pixel image is the exact same file whether your software labels it as 72 DPI or 300 DPI. The pixel dimensions don't change — only the suggested print size changes.

Bottom line: When preparing images for EntryThingy, focus on pixel dimensions and ignore DPI entirely.

How to check your image size

• Mac: Right-click the file → Get Info → look under "Dimensions"
• Windows: Right-click the file → Properties → Details tab → look for "Width" and "Height"
• Phone: Open the photo → tap the info/details icon

How to resize your images

If your image is too small or too large, use Pixel Prep — a free tool built into EntryThingy:

1. Go to app.entrythingy.com/artist/optimize
2. Upload your image
3. Choose a preset (like "Jury Submission" for 1920px) or enter a custom size
4. Download the resized image
5. Upload it to your application

Common file types

Most calls accept JPG and PNG files. Some also accept GIF, TIFF, WebP, or video formats (MOV, MP4). The accepted file types are shown on each call's upload page.

iPhone users: iPhones save photos in HEIC format by default. If a call doesn't accept HEIC, you can either: - Change your iPhone settings: Settings → Camera → Formats → Most Compatible - Convert individual photos using a free online converter

File size limits

Most calls allow files up to 50MB. If your file is too large, try re-saving it as a JPG — this usually reduces the file size significantly with no visible quality loss.
