TL;DR
Fifty-five congratulations messages for a brother or a sister, sorted by what they actually pulled off: a result, a new job or promotion, a business or a big risk, and the quiet adult milestones like a first flat. Separate sets for writing up to an elder sibling and down to a younger one, because those two registers are nothing alike. Devanagari and Hinglish included, plus a short section on not making their win about you.
A sibling's congratulations is a different instrument
Three kinds of messages land on a sibling's phone the day something goes right.
The parents' message is warm and slightly formal — blessing-shaped, often in Hindi, usually the one that makes them tear up. The friends' messages are loud, in caps, with four emojis. And then there is yours, which has an advantage neither of the others has: you were there for the boring part.
You know about the year they nearly quit. You know which rejection they cried about and told nobody. You know the exact tone their voice went when they said "it's fine, I'll try again." Nobody else on that phone can write from inside that information.
So the shape that works for a sibling is almost always the same: one joke, then one completely straight sentence. The joke earns the sincerity. Without the joke it sounds like a parent; without the straight line it sounds like you didn't care.
Ten for a result or a graduation
Eight for a new job or a promotion
Six for a business or a genuinely big risk
The sibling who starts something is usually the one the extended family has opinions about. This is where a message matters most, because the doubt is loud and the support is quiet.
Six for the quiet adult milestones
The first rent agreement, the driving licence at twenty-nine, the first flat, the day they stopped asking home for money. Nobody sends a message for these and everybody remembers when someone does.
Six from a younger sibling, going up
Writing up to an elder brother or sister is oddly harder — the tone can slip into sounding like a parent, which is exactly what they don't want from you.
Six from an elder sibling, going down
देवनागरी — eight lines for a card or a long message
Hindi gives a sibling message the weight that English keeps joking away. These work for a card, a handwritten note, or the citation line on a certificate. Each copies with both scripts.
Hinglish — five for the family group or a status
Romanized Hindi is the register siblings actually type in, and it reads best on WhatsApp — no keyboard switching mid-sentence, and it fits a status without wrapping onto a third line.
Don't make it about you
Nobody writes this section and everybody needs it, because a sibling's win is the one piece of good news that can quietly sting.
If they got in and you didn't, if they're younger and ahead, if their salary just passed yours — none of that belongs in the message. Not even as a generous-sounding joke. "You've done in two years what took me six" reads as warm and is, on inspection, entirely about you. So does "at least one of us made it."
Keep the message inside their news. Nine words with a fact in them. Feel whatever else you're feeling somewhere that isn't their phone, on a day that isn't today.
Two related boundaries worth holding: don't attach advice ("now do the next one") to a congratulations, and don't post it publicly before they've announced it themselves. Results and offers are family-political in India, and a proud story on Instagram can reach an aunt before the person is ready.
Make it yours: the one edit
Every line above has one slot where a real detail belongs. Filling it is the entire difference between a message and a greeting.
Take a flat "bahut badhai ho" and turn it into "teen saal, teesri koshish, aur aaj tera naam list mein hai." Turn "all those months" into "February to July, when you stopped picking up my calls." Turn "the treat is on you" into the exact restaurant you have been arguing about since college.
The rule scales down as well as up: birthday wishes for a sister and birthday wishes for a brother run on the same edit, and if your sibling is in another city, miss you messages for a brother or sister far away is the version for the ordinary weeks between wins.
When the group chat has already said congratulations forty times
By evening their phone has a hundred messages and yours is somewhere in the middle of it. That's fine for a good day. It's a bit thin for something they worked years for.
If you want to hand them something that survives the week, digital gifts for a sister or brother that aren't junk compares the actual options honestly — including the free ones — and says which ones a sibling will genuinely open twice. The short version from our side: Lovely's I'm So Proud of You page is ₹49 and takes about eight minutes, and it works especially well for a sibling because the six medals can be six inside jokes with one real one hidden in the middle. Your dashboard shows the clap count afterwards.
A long, specific WhatsApp message is still a genuinely good gift and it costs nothing. The page wins on two things only: it lasts past the day, and it lets them clap for themselves.
"Siblings write the most honest congratulations on the internet," says Ganesh, Lovely's founder. "They're the only people allowed to be rude and sincere in the same sentence."
Frequently asked questions
What should I write to congratulate my brother or sister?
Something only a sibling could write. Parents send the formal version and friends send the loud version; your advantage is that you know the boring middle — the year they nearly quit, the rejection they hid from everyone. One specific detail from that stretch beats any amount of enthusiasm.
How is a sibling's congratulations different from a parent's?
Register. A parent's message is blessing-shaped and slightly formal; a sibling's can tease, and the teasing is what makes the sincere sentence land. The reliable shape is one joke, then one true line with no joke in it at all.
What do I say when my younger sibling achieves more than me?
Say the congratulations without the comparison attached. "You've done in two years what took me six" sounds generous and is actually about you. Keep your message entirely inside their news; process your own feelings anywhere else.
Is a short congratulations message enough for a sibling?
Yes, if it has one fact in it. "Proud of you" is a reflex. "Two years of that commute and you finally got out" is a message. Six specific words beat forty general ones, and siblings can smell a forward instantly.
What can I send my brother or sister besides a message?
A page built around what they did. Lovely's I'm So Proud of You template is ₹49 — a certificate with their name, six medals for six specific reasons, a photo exhibit and a tap-to-clap standing ovation. It works well for a sibling because the medals can be inside jokes.
