What size are most wedding invitations?

In the UK, A6 and A5 are the standard sizes for printed wedding invitations. A6 is roughly the size of a postcard and works well for a single card with the essentials. A5 is larger and often used when you want to include a separate order of service, a map or a details card. Square invitations are also popular, but they cost more to post and can be harder for guests to file. If you are sending e-invites, size matters less because there is no envelope or postage, but you should still think about how your design looks on a phone screen. Most e-invite templates are built for portrait orientation, so a 4:5 or 1:1 ratio works nicely. For printed invites, always check with your printer for their exact trim sizes and whether they offer matching envelopes. If you are making your own, remember that UK standard paper sizes are easy to buy and cut at home. The size you choose should reflect the amount of text you need, not just the look. A clear, readable invitation is more important than a trendy shape.
