The short answer
Write 1 to 3 sentences. The quote carries the general sentiment. Your own line carries the details. Name the friend, name one shared event, then close. Most friendship cards take 20 to 40 words in total.
A standard 5x7 card gives about 4 by 6 inches of writing space inside. That holds 60 to 80 words in average handwriting. You do not need to fill it.
- Front panel: 3 to 8 words.
- Inside, above the fold: 15 to 30 words.
- Below the quote: 1 line with your name and the date.
Match the quote to the occasion
Birthday
Use lines about time, age, or shared history. Skip jokes about age. The card gets read once and kept for years.
Thank you
Name the gift or the act first. A quote about gratitude works after the specific line, not before it. Send the card soon after the gift arrives.
Moving away
Quotes about distance and letter writing fit here. Add your new address under your signature.
Illness or loss
Keep it plain. "I am here" does more work than a poem. Skip humor unless the two of you have used it in hard moments before.
Apology
Put the action you regret in the first line. A quote cannot replace the apology itself.
No occasion
Send it with a date and one memory. Cards with no event behind them still get kept.
Attribution and copyright
Credit every quote you did not write. Author name first, then the book, speech, or song if you know it. "Anonymous" works when the source is not recorded.
Song lyrics and lines from poems carry copyright. A greeting card is not an exemption. Short phrases and titles are not protected, but a full line from a song is. Quote one line with credit, or put the idea in your own words.
Write your own line in 4 steps
- Name one event. "The 2019 move to Dallas."
- Name what your friend did. "You drove 6 hours with the truck."
- State the result in 10 words or less.
- Close with a forward-looking line, not a summary of the friendship.
Mistakes to avoid
- A quote longer than your own message.
- A quote that would fit any friend of anyone.
- No signature and no date.
- An uncredited line from a song or poem.
Cards ship with envelopes. Write the address by hand, add a stamp, and mail it. A card in a drawer does nothing.
