About the Diameter black filled icon
A plain circle is crossed by a straight diagonal line that ends in an arrowhead at each side, touching the circumference at both points to mark the full width across the center. It communicates diameter, dimension and size. Use it on product spec tables, pipe and fastener catalogs, CAD or drawing tool palettes, tire and wheel sizing filters, and engineering documentation.
The arrow runs at 45 degrees so both heads sit clear of the circle stroke and the measurement stays obvious without a label. Line weights match the circle itself. Pair it with radius, angle and length icons; add a numeric label beside it when used in spec sheets.
This is the solid black filled version of the diameter icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
