Safe zones

Social media safe areas.

What it does

Shows where TikTok, Instagram, Facebook and YouTube put their buttons, caption and account name on a vertical video, so nothing important ends up hidden underneath.

How

• Pick a platform, or All for the area that is safe everywhere.
• Post for an ordinary video, Ad for a sponsored one: ads add a button and a label, so their safe area is smaller.
• Zones darkens what gets covered; Lines only draws the safe area.
• The mock post shows roughly what the app puts on screen. It is only in the preview, never in the PNG.
• Export PNG and put it on a layer above your video (1080 × 1920, or 2160 × 3840 for 4K). Hide it before you export your video.

Where the values come from

The safe areas follow the layout of each app, with a little room around the buttons and text. They are careful measurements cross-checked between several guides, for posts and for ads (platforms only publish fixed margins for ads, which do not follow the layout). Checked in November 2026; apps change their layout from time to time.
