Home > Guides > Faxing legal-size documents
Yes, you can fax legal-size documents, but confirm the recipient can receive them first. Most fax services handle an oversized page by shrinking it to fit a standard page or by splitting it across two pages. Fine-resolution mode protects small print through the shrink, and wide tables or fine type are what usually break when a page is scaled down.
A fax signal carries a fixed page width (about eight and a half inches) with a flexible length, so a legal-size page is wider than a letter page only in theory: in practice the sender's side has to decide what to do with the extra three inches of length. Online fax services make this decision automatically. Traditional machines leave it to the receiving machine, which prints on whatever paper is loaded, usually letter. That is the source of most surprises: you faxed a legal page, and the other end prints it shrunken on letter paper with type too small to read, or split awkwardly across two sheets.
| Option | Best for | Watch out for |
|---|---|---|
| Shrink to fit | Contracts and forms where one page must stay one page | Type gets smaller; fine print may become unreadable |
| Split across two pages | Spreadsheets and wide tables that need full-size type | Tables can break mid-row; page numbering shifts |
| Convert to letter first | Anything the recipient must file or scan later | You must reformat the source document yourself |
If the document must stay whole (a signed contract, a deed), shrinking keeps the page intact but risks legibility. If readability matters more than page count (a spreadsheet, an invoice with a wide table), splitting across two pages keeps the type at full size. For anything larger than legal, splitting is really the only option: ledger-size pages and wide drawings do not survive being shrunk to letter.
Use fine-resolution mode. Fax machines transmit in standard or fine resolution, and fine mode doubles the vertical detail, which makes an enormous difference for small print, signatures, and handwriting that has been shrunk. If you are scanning the document yourself, scan at 300 dpi in black and white before sending: a clean source scan survives shrinking far better than a low-resolution one. Avoid faxing legal-size pages that are already photocopies of photocopies; each generation loses detail, and shrinking stacks another loss on top.
Two things. First, ask whether their machine or service accepts legal-size reception at all. Many office machines default to letter paper, and a legal-length transmission arrives either shrunken or split with no warning to the sender. Second, ask which format they prefer: some offices want one shrunken page because it files as a single sheet, while others want two full-size pages they can actually read. In the US and Canada, office defaults are letter-size, so legal-size faxing always deserves this one quick question. If the recipient says their machine handles legal paper, the simplest move is to fax it as-is and let their machine do the work.
