Wedding Envelopes UK — C5, C6 & 5×7 Sizes
It's easy to focus all your attention on the stationery inside and treat the envelope as an afterthought — but your guests pick up the envelope first. They hold it, turn it over and take it in before the card is even out. That first impression matters, and our wedding envelopes are made to match the care that's gone into everything inside them.
Our collection covers three sizes — C6, 5×7 and C5 — each precisely sized for the stationery formats in our range. Every envelope is made from smooth, high-quality paper with crisp edges and a secure closure, available in peel-and-seal or gummed finish depending on the colour. Choose a colour that coordinates with your suite, add address printing, and your mailing is ready to go.
Wedding Envelope Sizes — Which One Do You Need?
Not sure which size is right for your stationery? Here's a straightforward guide to all three.
C6 Wedding Envelopes — 114 x 162mm
C6 is the right size for A6 cards — so if you're sending Save the Date cards, RSVP cards or thank you cards in A6 format, this is the one. It's also the envelope for our accordion-fold wedding invitations, which fold neatly down to A6 size. A snug, professional fit with no movement inside — your stationery arrives exactly as it left us.
5×7 Wedding Envelopes — 133 x 184mm (i8)
If your invitation isn't an accordion fold, it's almost certainly a 5×7 — and this is the envelope for it. Our i8 envelopes at 133 x 184mm are the standard match for all of our flat wedding invitations, and work equally well for RSVP inserts and guest information cards at the same size. The most widely used wedding invitation format in the UK — and our most popular envelope.
C5 Wedding Envelopes — 162 x 229mm
C5 is the generous option — designed for larger suites, folded A4 inserts or anything that needs a bit more room to breathe, such as invitations finished with a wax seal. It's the same quality and finish as the rest of the range, just with the space to accommodate your most substantial stationery comfortably.
Envelopes are available with either a peel-and-seal or gummed closure depending on the colour — both give a clean, secure finish. Check the individual product listing for the closure type on your chosen colour.
Wedding Envelope Colours — Every Palette Covered
A well-chosen envelope colour can tie your whole stationery suite together. Whether you want a classic white or ivory to let the design speak for itself, a soft neutral like champagne or kraft, or something bolder to create contrast — our range has you covered. Every colour is chosen for a consistent, even finish, so what you see when you order is exactly what your guests receive.
Wedding Envelopes with Address Printing
If you've ever hand addressed a large batch of envelopes, you'll know how much time it takes — and how the handwriting tends to drift by envelope 60. Our professional address printing service takes it completely off your to-do list. We print each guest's name and address in clean, modern typography, with an optional return address on the reverse, and supply your envelopes ready to post.
It's one of those details that guests notice and couples are always glad they added — a polished, consistent finish across every envelope that carries the same care as the stationery inside. Add it to your order and your posting day becomes a whole lot simpler.
- Guest name and address printed on every envelope
- Optional return address on the reverse
- Clean, modern typography consistent across the full run
- Supplied complete and ready to mail

Frequently Asked Questions — Wedding Envelopes
What sizes are your wedding envelopes available in?
We offer three sizes: C6 (114 x 162mm) for A6 cards and accordion-fold invitations, 5×7 / i8 (133 x 184mm) for all flat wedding invitation formats, and C5 (162 x 229mm) for larger suites and folded inserts. A simple rule of thumb — if it's an accordion fold or an A6 card, it's C6. Everything else in our invitation range is 5×7, so it's i8.
Which wedding envelope fits a 5x7 wedding invitation?
Our i8 envelopes at 133 x 184mm are the correct match for 5×7 wedding invitations — the most popular format for modern UK wedding stationery. You'll get a precise, comfortable fit with no excess movement inside.
Which envelope fits A6 Save the Date cards and accordion invitations?
Both use a C6 envelope (114 x 162mm). Our A6 Save the Date cards are designed for C6, and our accordion-fold invitations fold down neatly to A6 — so the same envelope covers both. All other invitations in our range are 5×7 and take an i8.
What colours do your wedding envelopes come in?
We stock a wide range — white, ivory, champagne, kraft, black, grey, blue (dark and light), green (including light green), pink, red, burgundy, lilac, gold and silver. Use the colour filters above to go straight to the shade you're looking for.
Are your wedding envelopes peel-and-seal or gummed?
Both — it depends on the colour. Some colours are available with a peel-and-seal closure, others with a gummed finish. The closure type is listed on each individual product page, so you'll always know exactly what you're getting before you order.
Can you print guest addresses on the envelopes?
Yes — we offer professional address printing across all three envelope sizes. We print each guest's name and address in clean, modern typography, with an optional return address on the reverse. Your envelopes arrive ready to post, saving you hours of hand addressing.
How are your wedding envelopes delivered?
All orders are sent by tracked delivery, so you can keep an eye on your order from our studio in Surrey right to your front door. We serve couples across Surrey, London and the wider UK.
Can I order wedding envelopes separately, without stationery?
Absolutely — our envelopes are sold as standalone products, so you can order just the envelopes whether you're buying stationery elsewhere, topping up a previous order, or getting ahead of your mailing list.
