About the No Under Eighteen Sign black outline icon

The numerals 1 and 8 sit inside a plain circle with a diagonal bar cut across them, the standard prohibition form for an age limit. It signals adults-only content, restricted purchase and minimum age entry. Use it on age gates for streaming and gaming sites, alcohol and tobacco product pages, nightclub and venue door notices, parental control settings, or content rating labels in apps.

The ring, slash and figures are drawn at a single stroke weight, with the bar running corner to corner so it crosses both digits without hiding them. It sits beside other prohibition and warning marks such as no entry and no smoking. Place it near the confirm button of an age check, at 32 px or larger.

This is the black outline version of the no under eighteen sign icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
