About the No Under Eighteen Sign black outline icon
The word UNDER sits above a large numeral 18 inside a ring, with a diagonal bar struck across the whole circle in the standard prohibition format. It reads immediately as an age limit: no minors, adults only, restricted purchase. Use it on age-gate screens, alcohol and tobacco product pages, casino and dating app onboarding, cinema rating notices and venue door signage.
Type carries the whole design here: a condensed UNDER across the top, the 18 scaled large to fill the lower half, and the slash cutting corner to corner so the ban reads before the numbers do. It pairs with parental control, warning triangle and forbidden icons. Keep it at 32 px or above so the small UNDER lettering stays legible.
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.
