There are few wedding details as important as your wedding invitations. More than just functional, these pieces of stationery are the first peek your guests will have of the celebration to come. Everything from their design to their paper quality, to even their size, helps to set the tone for your special day.

With so many styles and formats, it’s essential to help you make a good choice and balance beauty with tradition, but also practical functions.
The Classic Choice: 5″ x 7″ (A7 Size)
The 5″ x 7″ invitation is still the traditional queen bee of wedding stationery. It’s classic, neutral, and used in many different cultures and types of weddings.
Why Couples Love the 5″ x 7″:

This is a size that provides a well-groomed, well-proportioned appearance, and it is a size that has proven itself over time. Whether your wedding style is traditional and grand or contemporary and simple, the 5″ x 7″ card fits just right.
Ample Space for Details
From names, dates, and locations to unique premium icons- there is plenty of space to fit your theme! Designers can work in calligraphy, monograms, or even photos without the layout feeling crowded.
Envelope Compatibility
An A7 envelope (5 1/4″ x 7 1/4″) in 80lb. Text weight, these envelopes are also made from high-quality 80lb. Text-weight paper. Since this size is so popular, you’ll be able to find matching stationery such as RSVP cards and liners. And as long as your suite weighs one ounce or less, you pay regular USPS First-Class postage.
Universal Appeal
This size is generally considered the most “acceptable” for formal occasions in many cultures. Selecting this one means your invitation feels purposeful and classic, regardless of your wedding style.
Popular Wedding Invitation Sizes
The traditional invitation size is 5″ x 7″, but not every couple follows tradition – they are choosing different sizes to help convey their personality and to make sure their invitations are not like everyone else’s invitations. Here are a few other favorites:
Petite Invitations (4.25″ x 6″)
- Style: Compact and chic.
- Best for: Couples who want a stark design with crisp lines.
- Pros: Uses less paper and perhaps saves some money on printing; feels modern.
- Cons: Space constraints might require you to include more enclosure cards.
This petite option is perfect to embrace sustainability while keeping your flair.
Square Invitation (5″ x 5″ or 6″ x 6″)
- Style: Symmetrical, contemporary, and eye-catching.
- Best for: Brides with a bold, modern sensibility.
- Pros: This one immediately stands out among a pile of getting-holiday-mail-is-exhausting mail. The square design is ideal for printing your custom designs.
- Cons: Check the latest postage rates; the USPS still has surcharges for non-machinable square envelopes.
These are most often chosen by couples who want their invitations to be ornaments in their households, and they are willing to incur the added postage cost to achieve the effect.
Tall or Slim Invitations (4 x 9.25)
- Also called the “slim” invitation, this design is a smooth alternative.
- Style: Tall, elegant, and modern.
- For Whom: Destination weddings, or events with logistical components (such as multi-day parties, travel instructions).
- Pros: Extra vertical room for detailed text without it getting too crowded.

The simplicity and efficiency of this structure are what make it beautiful. Many couples love the way it looks with ribbon wraps, belly bands, or embellishments.
Folded or Booklet Invitations
Every now and then, one card is just not enough to celebrate your wedding. Accordion or booklet invitations allow for more space and lend to a non-traditional style.

- RSVP Cards: 5″w x 5″h (paired with 4Bar envelopes)
- Details/Enclosure Cards: 4” x 6” or 4.25” x 5.5”
