How many programmes should you apply to?

The honest answer is six to ten for most people, and the reasoning matters more than the number.

Think of it as a budget with three currencies.

Money. Application fees, test score reports, transcript copies. Twenty applications is a serious sum before anyone has read anything — money that could have covered a test retake or a deposit.

Attention. Every application needs a tailored paragraph at minimum, ideally more. Your fifteenth application gets a fraction of the care your third did, and it shows. A committee reading a statement that could have been sent anywhere treats it accordingly.

Your recommenders’ patience. Each letter is real work for someone doing you a favour. Twenty submission requests is a burden, and a rushed recommender writes a shorter, vaguer letter — for all of them, including the ones you cared most about.

So the constraint isn’t ambition. It’s that quality falls as quantity rises, and the marginal application is the weakest one.

A shape that works:

2–3 likely — you’d genuinely attend, and your profile is comfortably above what they usually take. 3–4 target — a real but uncertain fit. 1–2 reach — you’d need things to go well.

That’s roughly 6–9. Add more only if you can genuinely tailor each one.

Two adjustments:

Funded PhDs justify fewer. Each requires supervisor contact and a genuinely specific proposal. Four well-researched PhD applications beat ten generic ones by a wide margin.

Very high uncertainty justifies more — an unusual background, or a big gap between your profile and your targets. But add to the likely end, not the reach end. More reaches doesn’t reduce risk; it increases cost.

If you’re applying to fifteen because you can’t tell which are realistic — that’s a shortlist problem, and adding applications won’t fix it.
