Drop in your artwork and find out whether it will actually print sharp at the size you want — judged against how far away people will stand, not a made-up 300 DPI rule. Then vectorize a logo, build a spec a shop can quote from, and send it to a print shop near you.

A vector logo has no resolution limit — it prints as cleanly on a business card as on a building. If all you have is a PNG or a JPG, trace it here.
Works best on flat, high-contrast artwork — not photographs
The things a print shop has to ask you for before it can quote. Fill them in once and send a job that can be priced immediately instead of a photo and a question.
Your artwork check, if you ran one, is included automatically so the shop can see the resolution situation before quoting.
The 300 DPI rule comes from things you hold in your hand. It has almost nothing to do with a banner. The eye resolves detail down to about one arcminute, which works out to roughly 3438 ÷ viewing distance in inches:
| Held at arm's length (12 in) | 286 DPI — this is where “300” comes from |
| Read across a room (3 ft) | 95 DPI |
| Storefront, from the pavement (10 ft) | 29 DPI |
| Building wall (30 ft) | 10 DPI |
| Billboard from the road (50 ft) | 6 DPI |
Past those numbers the extra pixels are invisible — they only make the file slower to handle. Below them quality drops off gradually rather than suddenly, which is why a banner at half the ideal figure still looks perfectly normal from the kerb. Shops often specify 100–150 DPI at finished size for large format anyway, as margin for ink spread and for people walking closer than anyone predicted.
