A Guide To Wedding Invitation Sizes

Size: 5” x 7”

Available Accessories: Matching RSVP, direction, and reception cards, belly bands, thank you cards, and more from the same design suite.

Look and Feel: The traditional wedding invitation size and the most popular choice at Minted. A classic 5" x 7" card gives you plenty of room for wording and accessories, and it works beautifully for everything from black-tie celebrations to relaxed garden weddings.

Size: 4.25” x 6”

Available Accessories: Matching RSVP, direction, and reception cards, belly bands, thank you cards, and more from the same design suite.

Look and Feel: A slightly smaller take on the classic invitation. Petite invitations feel modern and streamlined, and they’re a great option if you love a clean layout, have shorter wording, or want a more budget-conscious format without sacrificing style.

Size: 5.76” x 12.03” (5.75” x 4.75” when folded)

What it is: These “seal-and-send” designs already include return address printing, a built-in envelope, and a perforated RSVP postcard that’s addressed and ready for your guests to drop in the mail. Simply fold, seal with 3 clear stickers (included) on the center and both sides of the flap, and send—no separate envelope required.

Look and Feel: A modern, streamlined format that’s as convenient as it is eye-catching. Many couples choose all-in-one invitations when they want something unique, budget-savvy, and easy for guests to mail back.

Size: 6” x 6”

Available Accessories: Matching RSVP, direction, and reception cards, belly bands, thank you cards, and more from the same design suite.

Look and Feel: A bold, design-forward format that instantly stands out in the mailbox. Square invitations feel modern and elevated, but keep in mind that their non-standard shape usually requires additional postage.

Size: 6” x 8”

Available Accessories: Matching RSVP, direction, and reception cards, belly bands, thank you cards, and more from the same design suite.

Look and Feel: Minted’s largest wedding invitation size. Grand invitations offer extra space for your wording, custom monogram, or a favorite photo, and they create a dramatic, luxurious first impression for your guests.

Minted offers designs for many different host lines, whether you’re including both sets of parents, one set, or just you and your partner. The more names you add, the smaller your font will need to be, which can be tricky on petite, square, or all-in-one formats. If you need extra room or custom placement, you can add a design request or work with our wedding concierge.

If you want to share engagement photos or extra wedding details, look for layouts with photo space on the front or back of your classic, petite, square, or grand invitation. You can also add coordinating enclosure or reception cards if you’d rather keep the main card very clean. For help deciding what to include and how to phrase it, use our invitation etiquette and wording guide.

Your invitation size and shape should support the overall look you want guests to experience. A classic 5" x 7" card gives you room for accessories like direction cards, RSVP cards, reception cards, and belly bands to bundle everything together. If you want to include multiple inserts, an all-in-one invitation is not the best fit, since it already includes a built-in RSVP postcard instead of loose cards. Petite and square invitations can still use these accessories, but they create a slightly more compact, modern reveal when guests open the envelope.

Often, couples add rounded corners or scalloped edges to match the formality of their celebration. If you love decorative trims, start with a classic 5" x 7" or petite 4.25" x 6" flat format so there’s enough room to cut the shape cleanly. This small detail can make your invitations feel more special without changing the overall size you’ve chosen.

Your invitation size, format, and number of pieces all play a role in your total budget. Petite and all-in-one formats are often the most budget-friendly options, while larger sizes and layered suites tend to cost more. You’ll also want to consider paper types, embellishments like ribbons and wax seals, and how many inserts you’re adding, since these can increase postage. If you’re unsure about weight or cost, connect with Minted’s customer service team before placing your final order.

Before you mail your invitations, bring one fully assembled suite to your local post office. Ask them to weigh it, check the size and shape, and confirm whether it qualifies as a standard letter or needs extra postage or a non-machinable surcharge. This is especially important for square envelopes, thicker paper, multiple inserts, or special touches like wax seals or ribbon, and a quick check now helps ensure everything arrives on time.

The standard size for a wedding invitation is 5" x 7". This classic 5" x 7" format gives you plenty of space for your wording and is a safe choice if you want a traditional look. It also pairs easily with standard envelopes, which makes mailing straightforward.

The wedding invitation sizes Minted offers are: classic 5" x 7", petite 4.25" x 6", all-in-one 5.76" x 12.03" (about 5.75" x 4.75" when folded), square 6" x 6", and grand 6" x 8". Each size has coordinating envelopes and accessories, so your whole suite feels cohesive and polished.

To choose the right wedding invitation size for your wedding, start with your wedding style, how much information you want to include, and whether you prefer a traditional or more modern format. Classic and grand sizes work well for formal, layered suites, while petite, square, and all-in-one invitations feel more streamlined and contemporary.

The best wedding invitation sizes for including photos or extra details are the classic 5" x 7" and grand 6" x 8" formats, which provide the most room. You can also pair your main card with matching detail or reception cards if you’d rather keep the front of your invitation very clean.

The size of your RSVP card and enclosure cards should be slightly smaller than your main wedding invitation, often around 4.25" x 5.5" for a 5" x 7" card. When you order from Minted, RSVP and enclosure cards are designed to coordinate with your invitation size and envelope, so everything stacks and fits together smoothly.

Smaller wedding invitation sizes can be more budget-friendly, especially petite and all-in-one formats that use less paper and may include fewer separate pieces. Your total cost will still depend on your paper type, printing style, and how many inserts or embellishments you add.

You can mix different invitation sizes within the same wedding stationery suite, but most couples stick with one size for the main invitation so everything feels cohesive. Smaller sizes are usually reserved for RSVP, detail, and reception cards that are designed to coordinate with your primary invitation.

The envelope size you need for your wedding invitations should be about 1/4" larger than your main card in both height and width. For example, a 5" x 7" invitation typically uses an A7 envelope that measures about 5 1/4" x 7 1/4".

Square or non-standard wedding invitation sizes often do need extra postage or a non-machinable surcharge. This is especially true if your suite is heavy, rigid, or includes special touches like wax seals, so it’s always a good idea to have your post office check a fully assembled sample.

If you picked the wrong wedding invitation size, reach out to Minted’s customer service team or wedding stationery experts as soon as possible. They can help you explore other formats, suggest coordinating pieces, or recommend tweaks so your suite still looks and feels the way you want.
