A classic size for invitations, even sometimes called ‘invitation envelopes' or 'greeting card envelopes', these pretty greeting envelopes will make everyone on the guest list want to come to the party. Our sizing guides will help you to make the perfect paper sizing decision and get just the right envelope. A6 envelopes measure in at 4 3/4 x 6 1/2, which makes them the perfect fit for your 4 x 6 photos. Since the size is multipurpose, you can send a folded card, invitations, season's greetings, or use it as an announcement envelope as well, even envelopes for postcards! You can even use them as an inner envelope for your wedding invitations since they can fit inside many A-sized envelopes. These 4.75 x 6.5 envelopes are waiting for your mail! Color is important and it's the most common way people decide on their note card envelopes. Because of this, we decided that categorizing by color will be the most efficient way for you to pick your favorite one! As you start to click on the colors, you'll find an assortment of shades to choose from. Our collection of Red 4.75 x 6.5 Envelopes is perfect for the holiday season; we even feature an envelope with a red foil lining!
