Short answer: for most birthday parties, 4ft x 2ft or 5ft x 3ft is the sweet spot. Here's a more detailed guide by venue and occasion.
Sizes by Venue
Living room / hallway
3ft x 2ft (90cm x 60cm) is plenty. Fits above a fireplace, over a doorway, or at the top of stairs. Any bigger and it looks cramped indoors.
Kitchen / dining area
4ft x 2ft. Big enough to be the backdrop of family photos without dominating a smaller room.
Garden party (30+ guests)
5ft x 3ft. Readable across the lawn. Tie between fence posts, trees or a gazebo frame.
Village hall / community centre
5ft x 3ft or 5ft x 5ft. Has to carry the room — hang behind the top table or above the cake.
Restaurant / private room booking
4ft x 2ft or 5ft x 2ft. Landscape works best for a table length display.
Sizes by Age / Party Type
| Occasion | Recommended Size |
|---|---|
| Kids birthday (under 10) | 4ft x 2ft |
| Teen birthday (16/18/21) | 5ft x 3ft |
| Milestone adult (30, 40, 50, 60) | 5ft x 3ft or 5ft x 5ft |
| Surprise reveal banner | 5ft x 3ft (impact matters) |
| Photo banner with pictures | 5ft x 3ft minimum (needs detail space) |

Why We Cap at 5ft
BPSD prints up to 5ft x 5ft (1.52m x 1.52m). That covers every domestic and most community hall birthday banners. If you're doing a marquee with 200+ guests, you probably want to tile two 5ft banners together rather than go bigger.
