Quick answer
Choose a wedding greeting card that matches the formality of the wedding, the space you have to write, and how you'll deliver it. A standard 108 x 140mm card with a blank interior and a cream envelope covers most weddings; a mini card suits a gift tag or a small note. Write a short, specific message, and if you're giving a gift, keep the card separate from the gift receipt.
You've RSVP'd, picked an outfit, and maybe chosen a gift. The card is the last small decision, and it's the one people actually keep. A wedding greeting card does two jobs: it carries your message and it sits on a table or in a keepsake box long after the day.
This guide gives you concrete decision rules for size, finish, envelope, and message, plus honest trade-offs so you don't overthink a card that takes two minutes to write and years to reread.
Start with size: standard vs. mini
Most wedding cards follow a standard format of 108 x 140mm (4.25 x 5.5 inches). That size gives you room for a real message, fits a standard envelope, and sits well in a card box or on a gift table. If you're writing more than a few sentences, or you're including a gift card or check, standard is the safer choice.
Mini cards, like the Adore You Hazelnut Ripple Mini Greeting Card at 98 x 67mm (3.8 x 2.6 inches), are better as a tag or a quick note attached to a physical gift. The trade-off is real: a mini card leaves little room for a heartfelt message, and it can look lost on a large gift table. Choose mini for a small, specific purpose, not as your main card.
Adore You Hazelnut Ripple Mini Greeting Card
- Standard 108 x 140mm: best for a full message, cash, or a check.
- Mini 98 x 67mm: best as a gift tag or a short note with a wrapped present.
- If you're unsure, standard size rarely feels wrong.
Match the finish and envelope to the wedding style
Foil stamping and envelope color do more for the feel of a card than the cover design. Gold metallic foil reads warm and traditional, which suits most weddings, while a cream envelope is a neutral default that won't clash with a venue's color scheme. A blush envelope, like the one on the You Complete Me Greeting Card, adds a softer, more romantic tone.
These are small signals, but they matter when a card sits on a table with fifty others. If the wedding is black-tie or formal, a foil-stamped card with a cream envelope fits in. If it's a backyard celebration, the same card still works; a mini card with a casual message also works.
- Gold foil + cream envelope: safe for formal and traditional weddings.
- Blush envelope: a softer option for romantic or pastel palettes.
- Blank interior: gives you full control over tone and length.
Write the message: short, specific, and signed
Wedding card etiquette is simpler than it looks. Address the couple by name, congratulate them on the marriage (not just the wedding day), and add one specific detail you appreciate about them or the celebration. Then sign your name, and your partner's if you're writing as a couple. That's it. You don't need a poem.
If you're stuck, use this structure: 'Congratulations to you both. [One specific memory or wish.] We're so happy for you. Love, [names].' For a gift card, write the amount or gift name on a separate note or the back of the card, not on the front. Never write 'congratulations' to a couple you know is already married; use a warm note about their life together instead.
- Use both names: 'Dear Alex and Sam,' not 'Dear Alex and guest.'
- Congratulate the marriage, not just the party.
- Sign legibly; the couple will want to know who the card is from.
Pair the card with your gift without awkwardness
If you're giving cash or a check, place it inside the card rather than loose in an envelope. If you're shipping a gift, put the card in the box on top of the item, or hand it to the couple separately. The card should never be the only place a gift amount appears, because cards get separated from gifts at busy weddings.
For a physical gift, a mini card tied to the ribbon works well, but only if you're also writing a full message elsewhere or you're comfortable with a short note. If the gift is the main event, use a standard card and write a real message. The card is not the gift; it's the part that explains why you chose it.
- Cash or check: inside the card, never loose in the envelope.
- Shipped gift: card on top inside the box, or hand-delivered separately.
- Mini card: fine as a tag, but don't rely on it for your main message.
Decision rules for your wedding card
- If you're writing more than three sentences: Choose a standard 108 x 140mm card so your message has room to breathe and the card doesn't look cramped. Standard size is the safe default for a main wedding card.
- If the card is a tag on a wrapped gift: A mini card like the Adore You Hazelnut Ripple Mini Greeting Card works, but keep the message to a line or two and sign it clearly. Mini cards are for short notes, not full messages.
- If the wedding is formal or traditional: Pick a foil-stamped card with a cream envelope; the gold foil and neutral envelope fit the setting without competing with the couple's colors. Cream envelope plus gold foil is the low-risk combination.
- If you're giving cash or a check: Place it inside a standard card, not a mini one, and write both names on the card so the couple can match the gift to you. Never send cash loose in an envelope.
- If you're unsure what to write: Use the structure: congratulate the couple, add one specific detail, sign both names. Skip generic lines about the wedding day. One specific detail beats a long generic message.
Cards that fit the rules
- Adore You Hazelnut Ripple Mini Greeting Card: Mini foil greeting card at 98 x 67mm (3.8 x 2.6 inches), white uncoated card stock, full-color plus gold metallic foil, blank interior, cream envelope, made in Australia. A good fit when you need a small tag or a quick note, but too small for a full wedding message.

The blush envelope gives a softer look than a cream envelope, which suits romantic or pastel wedding palettes.
- No Sleep Club Powder Stripe Greeting Card: Standard 108 x 140mm foil greeting card, uncoated card stock, full-color plus gold metallic foil, blank interior, cream envelope, made in Australia. A standard-size option with a cream envelope for a traditional or formal wedding, with room for a full message.
Who this approach fits
Best for
- Guests who want one card that works for most weddings without overthinking it
- Anyone writing a message longer than a sentence or two
- Guests giving cash, a check, or a gift that needs a card on top
Not for
- Anyone who only needs a tiny tag and no real message; a mini card alone is enough
- Couples sending their own thank-you notes; that's a different card and a different message
- Anyone looking for a pre-written verse; blank interiors are the point here
A wedding greeting card doesn't need to be perfect, just specific. Pick a standard card with a blank interior for most weddings, use a mini card only as a tag, and write a short message with both names and one real detail. That's the whole decision.
