A4 vs. Foolscap Paper Size: Key Differences & When to Use Each
A4 measures 210 × 297 mm, the global standard. Foolscap is 216 × 343 mm—slightly longer and narrower, a British imperial relic.
People confuse them because office drawers, folders, and old filing cabinets often say “Foolscap” while printers default to A4. Spot the extra centimetre by holding a sheet against an A4 pad; Foolscap sticks out like a tongue.
Key Differences
A4 fits every copier and binder worldwide; Foolscap overshoots the tray. Foolscap’s extra length once let typists squeeze a footer or note; A4’s tighter ratio matches modern PDF margins.
Which One Should You Choose?
Use A4 for resumes, contracts, and anything you’ll scan. Keep Foolscap for vintage legal files or if your office still stocks green-bar continuous forms—otherwise, recycle the stash.
Can I force Foolscap through an A4 printer?
Only if the feed slot is adjustable; expect edge creasing and toner smears.
Is A4 cheaper?
Yes—global demand drives bulk pricing, while Foolscap now carries niche markups.
Why do lawyers still say “Foolscap brief”?
Habit. Modern chambers actually print on A4, but the term survives like “cc” in email.
