2. Understanding Visual Safe Zones
Social platforms render timestamps, profile names, like buttons, and caption overlays directly on top of your artwork: - YouTube Video Length Badge: YouTube places a black duration badge in the bottom-right corner of thumbnails. Keep logos and critical focal text in the upper two-thirds and left side of the 1280×720 canvas. - Instagram Stories & Reels UI: Top 250px is obscured by account handles and status bars; bottom 250px is obscured by audio tags and message inputs. Center all core messaging. - LinkedIn Profile Header Cutout: The circular profile photo overlaps the bottom-left corner on desktop and center on mobile. Keep header text aligned to the right side.

Frequently Asked Questions
Why does Instagram blur my high-resolution photos?
If you upload an image wider than 1080px or in an unsupported aspect ratio, Instagram's aggressive server-side compression re-samples your photo. Resize to exact 1080px width prior to uploading.
What is the best format for YouTube thumbnails?
JPG or WebP with dimensions of 1280×720 pixels under 2MB. Use high contrast and saturated colors to stand out on dark-mode feeds.
