Flat vs folded baby thank you cards — which format should you choose?

Flat baby thank you cards: clean, photo-first and quick to write

Flat cards are a single, sturdy piece of card—no fold—ideal when you want a striking, full-bleed photo and a short message. They’re available in A5 (210 × 148 mm), A6 (148 × 105 mm), square 148 × 148 mm and 5″ × 7″ (127 × 178 mm). You can personalise the front and back, add a printed note, include extra photos, or drop in a scannable QR code linking to an online gallery—handy if grandparents would love to see more pictures.

Why parents pick flats

• Strong visual impact. One standout newborn photo on the front looks elegant and modern. Try our curated selection of photo baby thank you card designs if you’re going image-led.
• Speed. With a short printed message on the back, you can sign and address quickly—ideal during those sleep-deprived early weeks.
• Paper choices that feel luxurious. In addition to smooth and lightly textured options, flat cards can be printed on an ultra-impressive Super Thick 650gsm stock for a tactile keepsake feel.
• Pen-friendly finish. All Utterly Printable card stocks are uncoated and easy to write on, so handwritten notes are a pleasure.
• Digital flexibility. Prefer to send your thanks by email or print locally? There’s a high-resolution digital download option.

Design notes for flats

• Consider a collage layout if you can’t choose just one picture—multi-image templates are available.
• If you’re building your colour palette around the photo, minimal palettes such as white baby thank you cards keep the focus on your image.
• For a gentle, baby-blue accent, explore our blue baby thank you cards.

Folded baby thank you cards: extra space and a classic keepsake

Folded cards open like a booklet, giving you the front cover plus inside left, inside right and the back for thoughtful messages and extra imagery. They come in the same four sizes as flats and are professionally pre-scored to prevent cracking across the spine—so they open crisply and look polished even on thicker stocks. You can choose a top-fold landscape or a side-opening portrait layout.

Why parents choose folded

• Room to write. If you’d like to mention the gift, say something personal, or include a longer update, folded cards give you generous writing space.
• More design real estate. Add additional photos inside, a printed message, or a discreet QR code to a larger photo album at no extra personalisation cost.
• Heirloom appeal. Folded cards feel like mini keepsakes—lovely for grandparents to pop on the mantelpiece.

Design notes for folded cards

• A portrait front with a single photo and a clean headline feels timeless; consider neutral palettes like our ivory & cream baby thank you card designs.
• If you prefer a text-first cover with a small inset photo, browse the main collection of personalised baby thank you cards to find styles that put your words centre stage.

How to decide: size, paper, photos, envelopes and postage

When both formats look lovely, these practical points usually tip the balance:

1) Message length and handwriting

• Go flat if you’ll write a short line or two; print a thank-you note on the back and add a handwritten sign-off.
• Go folded if you want a longer message for each recipient, or if you’re including a poem, quote or mini birth update.
  All card stocks are uncoated and pen-friendly, so fountain pens and rollerballs behave nicely.

2) Your photo plan

• One hero image? Flats excel at full-bleed photos and clean typography. See our dedicated photo-led templates.
• Several favourites? Folded cards make it easy to add a collage inside, or you can choose a flat collage layout. Either way, you can include unlimited photos in the online designer.

3) Adding a QR code

If you’ve created a shared album or video, add a scannable QR code to your design. It sits neatly on the back of a flat card or on an inside page of a folded card, keeping the cover uncluttered.

4) Sizes and orientations

• Both flat and folded formats are available in A5, A6, square 148 × 148 mm and 5″ × 7″.
• Folded cards can be top-fold landscape or side-opening portrait, which can influence cover photo choice and how the card displays on a shelf.

5) Paper stocks and print finish

Choose from four premium, FSC-certified stocks—each writable and fully recyclable:

• House 350gsm bright-white matt: smooth and versatile.
• Premium 324gsm lightly textured off-white: a sophisticated, tactile finish.
• Photo Silk Touch 400gsm bright white with a silky light sheen: superb for photo-heavy designs and crisp colour reproduction.
• Super Thick 650gsm double-ply, lightly textured off-white: available for flat cards only for a truly luxurious feel.
  For photo-centric designs, Photo Silk Touch often delivers the most polished result; for understated, text-forward styles, Premium’s texture adds charm.

6) Envelopes, addressing and keepsakes

• Matching premium envelopes are available at checkout, supplied flat with a gummed flap for easy sealing.
• If you’re hand-addressing, a flat card can be quickest; if you’re creating a keepsake, many families prefer the gift-like feel of a folded card on the mantel.
• Both formats are sturdy enough to store in a memory box; flats can be mounted in albums, while foldeds can hold extra printed notes inside.

7) Printing, delivery and sustainability

• Cards are printed in the UK with fast turnaround: standard production in 3 working days or express in 1–2 working days (6 pm cutoff), followed by tracked UK delivery options including DPD next-working-day and Royal Mail Tracked 24.
• If you’re in the Scottish Highlands or Northern Ireland, allow an extra 1–2 days for delivery.
• Prefer a paper-free option? Choose the digital download to share your design online or print locally.
• All stocks are FSC-certified, plastic-free (no laminates or glitter), and there’s an optional carbon-offset contribution at checkout.

8) Budget and peace of mind

Printed samples are available for a small fee if you’d like to check colours and paper before ordering, and you can also order paper sample packs (currently £3.49) to feel the stocks at home. The online designer offers near-total editing freedom with live preview, so you can tweak fonts, colours and wording until it’s just right.

At-a-glance recommendation

• Choose flat if you want a bold photo on the front, quick addressing, optional Super Thick stock, or a neat QR code on the back.
• Choose folded if you need more writing space, plan to include extra photos inside, or love the gift-like, keepsake feel.
