# AI Birthday Card Generator

> An AI birthday card generator designs the whole card — artwork, layout and the greeting and name lettered in — from a short description. On Kenerate AI, GPT Image 2.5 Sunburst writes the words you put in quotes, such as “Happy 40th, Maya”, at 7.2 credits a design at 1K (12 at 2K); Recraft V4.1 and Ideogram v4 suit type-led cards. A printed 5×7 card needs about 1500×2100 pixels, so render at 2K or upscale and check the name letter by letter. It's built for cards for adults, couples, friends and pets — Kenerate's moderation blocks prompts about children and babies.

## In depth

### Birthday card sizes, ratios and pixels
Pick the ratio before you generate, so the name doesn't get cropped. Pixels are at 300 DPI:
- 5×7 in (A7, envelope 5.25×7.25 in), the standard: 3:4, trim a little off the sides; 1500×2100 px.
- 4.25×5.5 in (A2), the small note card: 3:4 fits closely; 1275×1650 px.
- 4.5×6.25 in (A6): 3:4; 1350×1875 px.
- 5.5×8.5 in (A9), a large card: 2:3; 1650×2550 px — render at 4K or upscale.
- 6×6 in square (6.5×6.5 in envelope): 1:1; 1800×1800 px. Square envelopes cost extra postage in the US.
- 4×6 in postcard, no fold: 2:3 fits exactly; 1200×1800 px.
- Folded cards print flat: a 5×7 is a 10×7 in sheet, plus 0.125 in bleed on every edge. Make the front as one image and the inside as another.

### Who this birthday card maker is for
Cards for grown-ups and pets: partners, parents, grandparents, friends, coworkers, clients, and the dog who's turning ten in dog years. Milestones from the 21st up work well — the number in quotes, large, is one of the easiest things for a model to letter.
Kenerate's moderation blocks any prompt that mentions children, kids, babies, toddlers, teens or an age under 18, and you can't switch that off. So there are no kids' party cards or first-birthday designs here; for those, use a template shop rather than an AI image tool.

### Why names come out wrong, and how to fix it
Image models draw letters as shapes, so they slip on long or unusual names, small text and long messages. A short greeting, the name in quotes and spelled out, a named letter style (“gold script”, “bold sans-serif”) and a clear position help most. When one letter is wrong, Edit Studio's Edit Text in Image swaps just that word and keeps the design — faster and cheaper than a new card.

## FAQ
Q: How do I make a birthday card with AI?
A: Open Kenerate's Image Studio, pick GPT Image 2.5 Sunburst and a 3:4 ratio, and describe the card: the style, the colours, and the greeting and name in quotes with where they go — “Happy Birthday” in gold script at the top, “Jordan” large below. Generate, zoom in on the lettering, then download. A design costs 7.2 credits at 1K or 12 at 2K.

Q: Is the AI birthday card generator free?
A: Free to start. A new Kenerate account gets 25 credits on sign-up — enough for three GPT Image 2.5 Sunburst card designs at 1K — and Qwen Image 3.0 is a free-plan model. After that, credits come in one-time packs that never expire, with no subscription. Downloads have no watermark.

Q: Will the AI spell the name right?
A: Usually, if you help it. GPT Image 2.5 Sunburst is the first pick for short greetings and names in quotes; Recraft V4.1 and Ideogram v4 are built for type-led designs. Any model can still drop or swap a letter, most often in long or unusual names, so spell the name out in the prompt, zoom in before printing, and fix a wrong letter with Edit Text in Image.

Q: What size should a printed birthday card be?
A: The everyday size is 5×7 inches (A7) in a 5.25×7.25 in envelope; A2 (4.25×5.5) is the smaller note card. At 300 DPI a 5×7 front is 1500×2100 pixels and a folded card prints flat at 10×7 in, plus 0.125 in of bleed on every side, per 4OVER4's card size guide. Square 6×6 cards look good, but the USPS charges extra postage for square envelopes.

Q: Can I put our photo or my pet on the card?
A: Yes. Add a photo of yourself, the two of you, a friend who agreed, or your pet as a reference, describe the card around it and add “keep the face exactly the same”. A GPT Image 2.5 Sunburst edit with one photo costs 11.7 credits at 1K. Nano Banana 2.1 is the pick when you want the same face or pet across several cards.

Q: Can I make a birthday card for a child?
A: No. Kenerate's moderation blocks prompts that mention children, kids, babies, toddlers or ages under 18 — every time, with no setting to turn it off — so this tool isn't for kids' cards, first-birthday cards or children's party designs. It's for adults' milestones (21st, 30th, 40th, 50th and beyond), partners, friends, coworkers and pets.

Q: Can I make a funny birthday card?
A: Yes — describe the joke as a picture: “a grumpy cat in a tiny party hat glaring at a cupcake, ‘Another year, another nap’ in bold comic letters”. Keep the joke to one short line on the front; long punchlines are where lettering slips. Only use photos of friends who'd enjoy it.

Q: Can I make a card for a coworker or a team?
A: Yes. Ask for a clean, office-friendly design — “confetti in our brand blue, ‘Happy Birthday, Priya!’ in bold sans-serif, ‘From the whole design team’ small below” — and add your logo as a reference if you want it on. Models can redraw a logo slightly, so place the original logo in an editor for brand-critical cards.

Q: Can I send it as an e-card or add a birthday song?
A: Yes. Download the image and send it by email or message, or post it — 4:5 or 1:1 for feeds, 9:16 for stories. Kenerate's AI birthday song generator can make a short song with their name to send with it.
