Match image width to the rendered container, not the camera source file. A clean resize pass often produces bigger performance gains than compression tweaks alone.
Use fixed dimensions for shared layouts and campaigns. Keep aspect ratio locked unless a channel requires a very specific crop shape.
The best size is the smallest dimension that still looks sharp in its final layout. As a practical baseline: 1600-1920px for heroes and 900-1200px for in-article visuals.
Downscaling usually improves visual cleanliness and helps performance. Upscaling can introduce blur or artifacts, so keep originals and avoid enlarging small sources unless necessary.
The key sizes change over time, but standard starting points include 1080x1080 (Instagram), 1200x630 (Facebook), 1200x675 (X), 1200x627 (LinkedIn), and 1280x720 (YouTube thumbnail).
Yes, for most production workflows you should lock aspect ratio to prevent distortion. Unlock only when a channel requires a forced canvas size and you have already accepted that tradeoff.
