C6 envelope – The classic choice for cards and letters

DIN C6 dimensions and formats: What fits in a C6 envelope?

The dimensions of a C6 envelope are specified in the DIN standard as 114 x 162 mm. This size is perfectly designed to securely hold various paper formats. Thanks to the standardized DIN C6 dimensions, this envelope is a true all-rounder:

• DIN A6: Postcards or simple cards fit perfectly without creasing.
• DIN A5: Folded in half, an A5 sheet fits perfectly into a C6 envelope.
• DIN A4: If you fold an A4 sheet once crosswise (quartering), it fits exactly into a C6 envelope.
• Additional formats: The C6 envelope is also a popular choice for business cards, small brochures, or flyers.

Material diversity and grammages: Quality you can feel

At Kuvertwelt.de, we place great importance on the feel and quality of our products. As you already know, not all of our papers have a standard weight of 100g/m². We offer a range of different weights to suit every occasion. A lightweight 80 g envelope is ideal for everyday use and optimized postage, while heavier papers from 120 g offer a particularly high-quality and exclusive feel that will immediately impress your recipients.

Colored envelopes C6 – The right design for every occasion

Colors evoke emotions and ensure that your mail immediately stands out in the mailbox. Our colored C6 envelopes are available in a huge range of colors:

• Classic & elegant: cream, white, and subtle pastel shades for stylish correspondence.
• Festive & Shiny: High-quality envelopes in gold or silver for Christmas and anniversaries.
• Pure nature: C6 envelopes made from kraft paper for an eco-friendly and trendy vintage look.
• Transparent: Our transparent C6 sleeves with a milky appearance provide an exciting first glimpse of the contents.
• Bright & bold: Vibrant red, deep blue, sunny yellow, or green —perfect for invitations or marketing campaigns.

Sealing types: wet adhesive, pressure-sensitive adhesive, or self-adhesive?

Depending on how you process your C6 envelopes, we offer different closure options:

• Wet adhesive (gummed): The classic with a pointed flap. The adhesive is activated by moistening—ideal for invitations that are inserted into envelopes by hand.
• Press-and-seal: Equipped with a practical peel-off strip. These C6 envelopes can be sealed quickly and cleanly and have a long shelf life.
• Self-adhesive: The two adhesive surfaces stick together simply by pressing them together.

Additional options: C6 with or without window?

For business use or letters with address fields, we offer C6 envelopes with windows (window position according to DIN standard: usually 15 mm from the bottom and 20 mm from the left). If you prefer to write the address by hand or prefer an elegant design without interruption, choose our versions without windows. Many of our premium models also feature an elegant silk lining, which provides additional opacity and a luxurious feel.
