Paper Envelopes Size Guide
Which envelope size should I choose?
We stock envelopes in various sizes and formats. Here are some recommendations:
C5 Envelopes (16.2 x 22.9cm)
C5 envelopes are best for large A5-sized invitations. But C5 also fits a folded A4 invitation, or any A4 document folded in half.
C6 Envelopes (11.4 x 16.2cm)
C6 envelopes are best for A6 invitations, folded-A5 greeting cards or documents. You can fold a A4 sheet twice and it will fit into C6.
Is C6 the same as A6?
No, C6 is slightly larger than A6. An A6 sheet fits perfectly into a C6 envelope.
Use C6 Envelopes to Protect Postcards
You could use C6 envelopes as postcard envelopes. Standard postcards are typically printed in the A6 format (10.5 x 14.8cm). You can easily fit multiple postcards into an C6 envelope, which will give them an extra layer of protection.
C6 Envelopes for 4 x 6 Photos
In the same way, C6 envelopes are perfect for storing photos or wrapping wedding pictures.
The most popular format is 4x6 photo prints (ca. 10 x 15cm), which will neatly fit into an C6 envelope.
C7 Envelopes (8.3 x 11.2cm)
C7 envelopes are comparatively small and therefore ideal for small A7 cards, a popular size for save-the-date or RSVP cards. C7 also takes a A6 document folded half.
DL Envelopes (11.0 x 22.0cm)
DL envelopes (or DIN Long) are popular with bookmark-style invitations or DL thank-you cards. You get DL when you cut an A4 sheet in thirds.
Square Envelopes (15.5 x 15.5cm)
Our square envelopes measure 15.5 x 15.5cm and fit all 14.8 x 14.8cm cards (usually large square greeting cards). They're also great to wrap CD-sized items.

What's the paper weight of your envelopes?
All ribbed kraft envelopes and colour envelopes have 100gsm. That's heavier than your standard office envelope (usually 70-80gsm). You can be sure that they'll still look great when they arrive in the recipient's mailbox, because 100gsm envelopes don't tear easily.
Fleck envelopes are a bit thicker at 110gsm and feel a bit sturdier.
What's the difference between Kraft and Colour Envelopes?
Rough texture and rustic look. Among the many types of envelopes available, kraft paper envelopes do definitely stick out.
No other type of envelope can give your correspondence such a retro, vintage look. Perfect for vintage-themed wedding invitations, save-the-date cards, or any other special occasion where you want to add that little extra to your stationery.
The earthy-brown colour of our kraft envelopes goes really well with bold-coloured paper as well as muted tones.
For kraft wedding invitations, we can highly recommend combining your envelopes with brown jute twine, white lace, or dried flower petals for a classic vintage look.
Seal the envelopes with a wax seal for the perfect finishing touch.
Planning to print on kraft envelopes?
Brown kraft paper will slightly change the appearance of colours when you print on it. It's best to try out different colours and see what gives you the best contrast with your printer.
For the best possible contrast, we recommend to stick with darker colour tones, such as black.
