What Size Is a Greeting Card? Standard Card Sizes Explained
If you're buying, making, or mailing a greeting card, you may wonder what size a greeting card usually is. While greeting cards come in many shapes and dimensions, there are several standard sizes that are commonly used for birthdays, thank you cards, weddings, holidays, and other occasions.
The most common greeting card size is approximately 5 x 7 inches (12.7 x 17.8 cm) when the card is closed. This size provides enough space for a front design, a personal message inside, and a standard envelope.
However, greeting cards can be smaller, larger, square, rectangular, or even unusually shaped.
In this guide, we'll explain standard greeting card sizes, common envelope dimensions, popular card formats, and how to choose the right size for your needs.
What Is the Standard Size of a Greeting Card?
A common greeting card size is 5 x 7 inches (12.7 x 17.8 cm) when folded.
This is one of the most popular formats because it offers a good balance between size and practicality. There's enough room for a printed design on the front and a handwritten message inside without making the card difficult to store or mail.
A folded 5 x 7-inch card starts with a flat sheet approximately:
10 x 7 inches (25.4 x 17.8 cm)
The sheet is folded in half to create the finished card.

There isn't one universal greeting card size, but common dimensions include:
4 x 6 inches
5 x 7 inches
5.25 x 5.25 inches
6 x 8 inches
8 x 10 inches
The size usually refers to the closed card, rather than the unfolded sheet of paper.
For example, a 5 x 7-inch folded greeting card is approximately 5 inches wide and 7 inches tall when closed.
What Size Is a Greeting Card in Centimeters?
For people who use the metric system, common greeting card sizes include:
10.2 x 15.2 cm
12.7 x 17.8 cm
13.3 x 13.3 cm

A 5 x 7-inch card is approximately 12.7 x 17.8 cm.
What Is the Standard Birthday Card Size?
Many traditional birthday cards are around 5 x 7 inches (12.7 x 17.8 cm).
This size works well because it provides enough space for:
A large birthday message
Illustrations or photographs
A personal message
A signature
Birthday cards can also be smaller or larger depending on the design.
For children, smaller cards can be fun and easy to handle, while milestone birthday cards may use larger formats.
What Size Is a Thank You Card?
Thank you cards are commonly available in sizes around 4 x 6 inches or 5 x 7 inches.
A smaller 4 x 6-inch card can be ideal for a short thank you message.
A 5 x 7-inch card is better if you want enough space to write a longer, more personal note.
For example, wedding thank you cards often benefit from a larger format because couples may want to thank guests for both their presence and their gifts.
What Size Is a Wedding Card?
Wedding greeting cards are commonly around 5 x 7 inches, although larger and square designs are also popular.
A 5 x 7-inch card provides enough space for a congratulatory message without being excessively large.
For a handmade wedding card, you can choose a larger format if you want to include photographs, elaborate decorations, or a longer message.
What Size Is a Christmas Card?
Christmas cards are available in many sizes, but 5 x 7 inches is a common format.
Holiday cards may also be:
4 x 6 inches
5 x 7 inches
6 x 8 inches
Square
Panoramic or landscape
Photo Christmas cards often use 5 x 7-inch dimensions because the format works well for family photographs.
What Size Is a Graduation Card?
Graduation cards commonly use the standard 5 x 7-inch format.
This provides enough space for congratulations on the front and a personal message inside.
You may also find larger graduation cards designed to accommodate longer messages or money gifts.
What Size Is a Sympathy Card?
Sympathy cards are often approximately 5 x 7 inches, although smaller cards are also common.
Because sympathy messages tend to focus on sincerity rather than elaborate decoration, a traditional rectangular format works particularly well.
A larger card can be useful if several family members want to write personal messages.
What Size Is a Greeting Card Envelope?
The envelope should be slightly larger than the folded card.
For a standard 5 x 7-inch greeting card, a corresponding envelope is commonly around 5.25 x 7.25 inches or slightly larger, depending on the card's thickness and construction.
If your card contains multiple layers, embellishments, or a three-dimensional design, you'll need an envelope with additional room.
Always check the actual dimensions of the card and envelope before purchasing them together.
What Size Is a Greeting Card When Open?
The size of a folded greeting card changes when you open it.
For example, a card that measures:
5 x 7 inches when closed
will measure approximately:
10 x 7 inches when fully open.
The same principle applies to other folded card sizes.
A 4 x 6-inch folded card would be approximately 8 x 6 inches when open.
This distinction is particularly important if you're designing or printing your own cards.
What Size Paper Do You Need to Make a Greeting Card?
The amount of paper you need depends on the finished card size.
For a 5 x 7-inch folded card, you'll generally need a piece of cardstock approximately 10 x 7 inches before folding.
For a 4 x 6-inch card, use approximately 8 x 6 inches of paper.
If you're making cards yourself, start with paper that is slightly larger than the finished dimensions and trim it after folding if necessary.
What Is the Best Greeting Card Size?
For most occasions, 5 x 7 inches is a versatile choice.
It works well for:
Birthday cards
Thank you cards
Wedding cards
Anniversary cards
Graduation cards
Sympathy cards
Christmas cards
Congratulations cards
Baby shower cards
The size is large enough for a meaningful message but small enough to fit comfortably in a standard envelope.
What Is a Small Greeting Card Size?
Small greeting cards are often around 4 x 6 inches or smaller.
Small cards are useful when you want to write a short message or attach a card to a gift.
They can work particularly well for:
Gift tags
Small thank you notes
Flowers
Gift baskets
Small presents
Party favors
A small card can still feel personal, especially when you write a thoughtful message by hand.
What Is a Large Greeting Card Size?
Large greeting cards can measure 6 x 8 inches, 8 x 10 inches, or even larger.
Large cards are useful when multiple people need to sign the same card.
For example, a large card can be useful for:
Retirement
Workplace celebrations
Milestone birthdays
Group congratulations
Farewell cards
Teachers
Team gifts
The extra writing space allows many people to add their own messages.
What Size Is a Square Greeting Card?
Square greeting cards come in many dimensions.
Common examples include:
5 x 5 inches
5.25 x 5.25 inches
6 x 6 inches
Square cards have a distinctive appearance and can be especially attractive for artistic, modern, wedding, and handmade designs.
Keep in mind that square envelopes may have different mailing requirements depending on where you live.
Does Greeting Card Size Matter for Mailing?
Yes. Card size can affect mailing requirements and postage.
A standard rectangular card is generally easier to mail than an unusually large, thick, rigid, or square card.
The final postage can depend on:
Dimensions
Weight
Thickness
Envelope type
Destination
Postal service
If you're mailing a handmade or unusually shaped greeting card, check the postal requirements before sending it.
What Greeting Card Size Is Best for Handwriting?
A 5 x 7-inch card is a good choice if you want enough room for a handwritten message.
It's large enough for several paragraphs without feeling like you're writing a letter.
If your message is very short, a 4 x 6-inch card may be sufficient.
If several people need to sign the card, choose something larger.
What Greeting Card Size Is Best for Photos?
A 5 x 7-inch card is also a popular choice for photo greeting cards.
The dimensions work particularly well with standard photographs, making it easy to create:
Birthday photo cards
Christmas photo cards
Anniversary cards
Wedding cards
Graduation cards
Family cards
You can use one large photograph or combine several smaller images.
What Greeting Card Size Is Best for Handmade Cards?
There isn't one perfect size for handmade cards.
However, 5 x 7 inches is a convenient starting point because cardstock, envelopes, and other supplies are widely available in compatible sizes.
If you're creating a more artistic card, you can experiment with:
Square cards
Mini cards
Oversized cards
Landscape cards
Tall cards
Pop-up cards
Just make sure you choose an envelope that fits the finished design.
What Cardstock Weight Is Best for Greeting Cards?
Card size isn't the only consideration when making a greeting card. The thickness of the paper also matters.
Cardstock is generally preferable to ordinary printer paper because it provides more structure and durability.
A medium-to-heavy cardstock can work well for most handmade greeting cards.
If you're adding several layers, embellishments, or pop-up elements, choose a sturdy card base that can support the additional weight.

How to Choose the Right Greeting Card Size
When choosing a card size, consider four things.
1. How Much Do You Want to Write?
If your message is only a few sentences, a small card may be enough.
For a longer message, choose a larger card.
2. How Many People Will Sign It?
A group card needs more writing space than a personal card.
For a card signed by an entire team or family, consider a larger format.
3. Will You Be Mailing It?
If the card is going through the mail, a standard rectangular size is generally easier to handle.
4. Does the Occasion Call for Something Special?
A standard 5 x 7-inch card works for almost anything, but an unusual size can make an important occasion feel more distinctive.
Greeting Card Size vs. Envelope Size
It's important to distinguish between the dimensions of the card and the dimensions of the envelope.
The card is measured when folded, while the envelope needs to be slightly larger to accommodate it.
For example:
Card: 5 x 7 inches
Envelope: approximately 5.25 x 7.25 inches or larger
The exact envelope size will depend on the thickness and construction of the card.
