C7 Envelope FAQs
C7 envelope dimensions are 81 x 114 mm (3.2” x 4.5”). This size is designed to fit an unfolded A7 sheet of paper or an
A7 blank card, an A6 piece of paper folded in half, or an A5 sheet folded into quarters. They are one of the smallest sizes of envelopes in the UK, and are smaller than
C6 envelopes. These mini envelopes are commonly used for RSVPs, save-the-dates, mini greetings or personal messages. Commercially, they can also be used for vouchers, loyalty cards and gift cards.

A C7 envelope is designed to snugly fit an
A7 card blank
or an A7
piece of paper
without folding. C7 envelopes measure 81 x 114 mm (3.2” x 4.5”), while A7 card blanks measure 74 mm x 105 mm (2.9” x 4.1”). There is a little extra space designed to allow you to easily insert the A7 card into the C7 envelope.
The C in the name C7 stems from the
ISO 269 standard,
which was established in 1975 and is now the standard for paper sizing across the world. All C-series envelopes
(C4,
C5,
C6
and
C7)
correspond to an A-series paper (A4, A5, A6 and A7). So, you should always pair your A-series
piece of paper
or
card blank
with the appropriate C-series
envelope
to ensure the correct fit.
C7 envelopes are one of the smallest sizes of envelopes and their small size makes them ideal for:
Special event or wedding RSVPs
Save the dates
Thank you notes
Mini greeting cards
Personal messages
Gift cards, vouchers or loyalty cards
Seed or confetti packets
C7 envelopes are one of the smallest envelope sizes available, measuring 81 x 114 mm (3.2” x 4.5”). While technically C8 envelopes are smaller, these are so small that they are rarely used, and typically C7 envelopes are the smallest size readily available. They are smaller than
C4,
C5
and
C6 envelopes.
At the Envelope People, we also offer a range of small envelopes with a variety of sizes, some of which are a similar size to C7 envelopes or even smaller, such as this
70mm Square Black Envelope.
In the UK, sometimes C7 envelopes are referred to as A7 envelopes (reflecting the size of card they are designed to accommodate). However, confusingly in the US, A7 envelopes are 5” x 7” - much larger than C7 envelopes in the UK. The A in this A7 stands for Announcement and is a common classification in the US stationery and crafting industry.
When buying C7 envelopes online, it’s important to check the dimensions to ensure it’s the right size, especially if purchasing from an international retailer.
