Tips for Writing a 12th Birthday Card for a Boy
Match his interests
At 12, boys are into coding, football, guitar, and BMX. Referencing something he specifically loves makes the card feel personal rather than generic.
Be genuine
12-year-olds can tell when a message is genuine versus generic. Reference a specific memory, inside joke, or something you admire about him.
Sign it with love
End with a warm closing that matches your relationship. 'Love,' for family, 'Your friend,' for classmates, or 'Happy birthday from your biggest fan' for that special touch.
Make it personal
The best birthday cards reference something specific about the person — a recent accomplishment, a shared memory, or something you are proud of him for.
