Vacay Alchemist"How many days do I need in Paris" or "3 days in Rome" searches get you a fixed number that ignores your actual pace and priorities. Here's a framework that works for any city instead.
Start with the neighborhood count, not the landmark list
Count the distinct neighborhoods or districts you actually want to spend real time in, not just landmarks to photograph — a city with 3-4 must-see districts needs roughly one relaxed day each, while a city where everything's within one compact center can work in fewer, longer days.
Add a buffer day for every planned day trip
Each day trip outside the city (a nearby town, a vineyard region, a coastal stop) needs its own full day, not a few borrowed hours from a city day — budgeting it as a half-day almost always means rushing both the city and the day trip.
Factor in your actual pace, honestly
A 'fast' traveler who wants 3-4 activities a day can compress a 5-day framework into 3-4 days; someone who wants real downtime and fewer scheduled activities per day should add a day rather than cram. Be honest about which type you actually are on past trips, not which type you'd like to be.
Build in one flex day for anywhere staying 5+ days
Trips of 5 or more days in one city benefit from at least one unscheduled day — for weather backup, a place you loved enough to revisit, or simply recovery. Itineraries with zero slack tend to feel like a checklist rather than a trip by day 4 or 5.
A rough starting range by city size
Compact, single-center cities (Florence, Prague) work well in 2-3 days. Mid-size cities with several distinct districts (Barcelona, Amsterdam) usually need 3-5. Sprawling multi-district capitals (Paris, Tokyo, London) genuinely reward 5-7+ days — treat any of these ranges as a starting point to adjust with the framework above, not a fixed answer.
Frequently asked
Is it better to see more cities for fewer days each, or fewer cities for longer?
Fewer cities for longer almost always produces a more relaxing, less transit-heavy trip — the time and cost of moving between cities is easy to underestimate when planning.
How do I know if I'm overplanning a city trip?
If your itinerary has zero unscheduled time across a 5+ day trip, that's a sign to cut something — a trip with no slack tends to feel exhausting rather than relaxing by the midpoint.
