Frequently asked questions

How tall should letters be?

Roughly 1 inch of letter height per 10 feet of viewing distance is a good start.

Do I need wind slits?

Wind slits help outdoors; the calculator suggests when to add them.

What dpi target should I pick?

100-150 DPI works for large format printing at long distances; the tool recommends values.

How far apart should grommets be?

Common spacing is every 24"; adjust based on width and hardware.

Can your team do this for me instead of using the online tool?

Yes. The browser tool is free and private, but if you would rather not rely on it alone, upload your files via our complimentary file uploader and request Human + AI help with “Banners”. Our prepress team will review manually — with AI assistance — and reply for free.
