Understanding Image Resolution
Resolution is measured in pixels — width × height. Higher resolution means more detail but also larger file sizes. The right resolution depends on where and how you'll use the image.
This guide covers optimal resolutions for AI image generators, social media platforms, display standards, mobile devices, and print.
Resolution Categories
AI Generators
Native resolutions for Stable Diffusion, DALL-E, Midjourney. Using correct sizes prevents artifacts.
Social Media
Optimal sizes for Instagram, TikTok, X, Facebook, LinkedIn, Pinterest, and YouTube.
Displays
Standard monitor and TV resolutions from HD to 8K, including ultrawide formats.
Print resolutions at 300 DPI for photos, posters, and standard paper sizes.
Pro Tip: AI Generator Native Sizes
Always use native resolutions for AI generators. SD 1.5 was trained on 512×512, SDXL on 1024×1024. Using different sizes can cause duplicated subjects, distortion, or quality issues.
Important: Print DPI
Print resolutions are calculated at 300 DPI (dots per inch) for high-quality prints. Lower DPI (150-200) is acceptable for large posters viewed from a distance.
Frequently Asked Questions
What resolution should I use for web?
For web use, 1920×1080 (Full HD) is usually sufficient. Most screens display at this resolution or scale down from it. For retina displays, consider 2×.
Can I upscale AI-generated images?
Yes! Tools like Real-ESRGAN, Topaz Gigapixel, and built-in upscalers in Midjourney and SD can upscale 2-4× while maintaining quality.
What's the difference between DPI and PPI?
DPI (dots per inch) refers to print resolution, while PPI (pixels per inch) refers to screen resolution. For digital work, the pixel dimensions matter more than DPI.
