Practical tips for creating consistent, scalable SVG icon sets for web and app interfaces.
Designing icons as SVG gives you scalable, styleable, lightweight graphics. Here are practical tips for creating icon sets that work well across web and app interfaces.
Use a Consistent Grid
Design all icons on the same grid — typically 24×24, 20×20, or 16×16 pixels. Set your SVG viewBox to match. This ensures consistent visual weight when icons appear together.
Optimize for Small Sizes
Icons are often displayed at 16-24 pixels. Avoid details that disappear at small sizes. Test every icon at its smallest intended display size.
Use currentColor
Set fill="currentColor" or stroke="currentColor" so the icon inherits the parent element's text color. One SVG file works in any color context.
Pixel-Align Strokes
If using stroked icons, align paths to the pixel grid to avoid blurry lines at small sizes. Use even stroke widths (2px, not 1.5px) and position paths on whole or half-pixel coordinates.
Converting Existing PNG Icons
If you have PNG icon sets that need to be SVG, batch convert them with Shape to Vector (up to 10 at once). Then optimize with SVGOMG and verify each icon at small display sizes.
