The Top 4 Greeting Card Sizes with Practical Tips

Greeting Card Size	Envelope Size	Common Uses	Marketing Strategy
5.0″ x 7.0″	A7 (5.25″ x 7.25″)	Business holiday cards, corporate appreciation, milestone celebrations	Premium branding with foil stamping & embossing, includes handwritten messages for a personal touch
4.0″ x 6.0″	A6 (4.75″ x 6.5″)	Thank-you notes, birthday cards, event follow-ups	Compact but professional, works well for loyalty rewards and post-purchase engagement
3.5″ x 5.0″	A1 (3.625″ x 5.125″)	RSVP cards, event invitations, gift enclosures	Cost-effective for direct mail, great for VIP invites and event marketing
4.25″ x 5.5″	A2 (4.375″ x 5.75″)	Invitations, brand promotions, seasonal greeting cards	Ideal for promotional use, direct mail, and product launch announcements

A. 5.0″ x 7.0″

The card size is perfect for business holiday cards, corporate
appreciation, and milestone celebrations. Greeting cards can also
exude premium branding using foil stamping & embossing. You can also
include handwritten messages for a personal touch

Why it works:

High-end branding opportunities (foil stamping, embossing, spot
UV)
More space for handwritten messages, making it feel personal and
valuable
Fits well with corporate gifting or outreach to high-value
customers

Practical Tips:

Choose high-quality paper stock (at least 14pt cardstock) to
enhance its luxurious feel.
You can also use a soft-touch or velvet finish for a more premium
tactile experience.
Add a surprise to the greeting card, whether it’s an exclusive
holiday discount, a VIP event invitation, or a QR code linking to
a custom video message sharing your greetings or gratitude.

B. 4.0″ x 6.0″

This compact but professional card size is perfect for thank-you
notes, birthday cards, and RSVP event follow-ups. You can also use
these greeting cards for loyalty rewards and post-purchase
engagement.

The best strategy is to mail these cards in bulk. The cards fit in
A6 envelopes, keeping mailing costs low, while also helping in
customer retention programs and post-purchase appreciation.

Why it works:

Compact yet professional—easy for bulk distribution
Fits in A6 envelopes, keeping mailing costs low
Ideal for customer retention programs and post-purchase
appreciation

Practical Tips:

Use personalization when designing these smaller greeting cards.
Variable printing such as customer names, personal messages, and
custom discount codes could increase their engagement.
Stick to simple, bold designs—too much text can make the smaller
card size look cluttered.
Go for matte finishes if you want recipients to write on them (for
RSVP or sign-in purposes).
If sending in bulk, consider digital printing over offset to keep
costs lower while still getting high quality.

C. 3.5″ x 5.0″

This card size is even smaller but also cost-effective. Use greeting
cards for direct mail, RSVP, event invitations, and gift enclosures.
The small size also ensures quick and easy-to-read messages and can
be tucked into product packaging for added engagement.

Why it works:

The size is smaller so make it stand out—use bold typography and a
clean layout to maximize visibility.
Consider a perforated design so it comes with a tear-off option
for discount cards or coupons.
Maximize its use as an invitation card—include a QR code that
leads recipients to a simple RSVP form online.

Practical Tips:

Make it stand out—use bold typography and a clean layout to
maximize visibility.
Use these as VIP or loyalty inserts—add a handwritten thank-you
note for a personal touch.
Consider a perforated design if it’s a tear-off discount card or
coupon.
Great for event RSVP cards—include a QR code leading to a simple
RSVP form online.

D. 4.25″ x 5.5″

At first glance, this card size closely resembles a postcard. And
while postcards could be more impactful, the A2 greeting cards are
cost-efficient for mass mailing. And they can fit in an envelope.

Use this card size for invitations, brand promotions, seasonal
greetings, and product launch announcements.

The size works well with variable printing for customized
invitations and can integrate into direct mail marketing strategies
and promotions.

Why it works:

More impactful than a postcard, yet cost-efficient for mass
mailing
Works well with variable printing for customized invitations
Seamlessly integrates into direct mail marketing strategies

Practical Tips:

Try customizing the greeting cards to look less than postcards.
Rounded corners or die-cut shapes can make the invitation look
unique.
Pair with an eye-catching envelope to boost open rates (e.g.,
metallic foil or colored envelopes).
Use a high-gloss finish to showcase photos or vibrant graphics
along with the message.
Add a unique call-to-action—for example, “Bring this card for a
free gift” at an event.
