Evergreen best-practice checklist
-
Upload bigger than display. Platforms down-scale gracefully; they never up-scale well.
-
Mind the crop-safe zones. UI chrome shifts every few months — leave 14 % padding top/bottom on Stories.
-
Stick to sRGB JPG/PNG at ≤ 100 KB for covers; avoid over-compression on logos.
-
Batch-export originals at 2× width so you can recrop when specs change.
-
Audit quarterly. If you’d like automatic alerts any time a dimension shifts, tell me and I can set up a scheduled check.
