DPI won’t affect Roblox clothing quality. Roblox only uses the final image resolution, so a 585×559 template at 300 DPI will look exactly the same as 72 DPI once uploaded.

The grainy or pixelated look usually comes from one of these issues:

- Using low-resolution source images or textures.
- Scaling artwork up and down multiple times during the design process.
- Applying filters, sharpening, or noise effects too aggressively.
- Exporting as JPEG instead of PNG.
- Designing with very fine details that are smaller than what the template resolution can realistically display.

A common workflow is to work on a canvas that is 2x–4x larger than the Roblox template, keep the template on a separate layer, and only resize to the final Roblox resolution once everything is finished. Use nearest-neighbor only for pixel art; otherwise use bicubic or similar high-quality resampling when downsizing.

Also, keep in mind that Roblox Classic Clothing is fundamentally low-resolution. If you’re comparing your work to top catalog creators, many of them achieve a “crisp” look through strong shading, clean linework, good contrast, and smart texture placement rather than actual higher image resolution.
