Why does Instagram crop my 4:5 asset differently on desktop versus mobile?

Feed shells vary padding and safe zones by device width. Export once from the preset page, upload privately, and screenshot both breakpoints before scheduling.

YouTube thumbnails: does 1280×720 still matter if YouTube downscales?

Higher starting resolution survives HQ badges and crisp preview scrubbing on TVs. Export at least the preset bucket linked here before letting YouTube recompress twice.

LinkedIn banners keep chopping our logo—how much bleed?

Company banners crop aggressively on mobile profile stacks. Keep logos inside the central safe corridor referenced by the LinkedIn preset pack and avoid thin borders touching edges.

Pinterest prefers vertical—but how tall before diminishing returns?

Pins taller than ~2.3:1 often get trimmed in discovery grids. Stick near the Pinterest preset ratios unless analytics prove ultra-tall outliers outperform for your niche.

Resource guide

Social media image sizes

Preset resizers for Instagram, YouTube, Facebook, LinkedIn, X/Twitter, and Pinterest plus thumbnail and story makers—stop guessing pixels.

Why presets beat manual typing

Every network recompresses uploads differently; starting close to native dimensions preserves detail longer before their encoders chew edges. Preset hubs encode institutional knowledge—1080×1080 squares for feeds, 1080×1920 for vertical stories, 1280×720 for YouTube thumbnails—so marketers spend time on creative, not arithmetic.

Beyond static sizes, creative starters like thumbnail and story makers accelerate campaigns when stock templates must match brand bars and safe zones. Pair them with compressors when platforms throttle bitrate on congested cellular networks.

Link previews deserve their own lane because Open Graph cards influence CTR more than in-feed dimensions. Validate crops where headlines meet imagery so automated shares do not clip product names.

Because creatives bounce between tools, we cross-link converters and compression utilities—ideal when a brand guideline mandates JPEG quality floors but the UI exports giant PNGs by default.
