TTRPG Settlement Demographics Calculator

D&D/TTRPG용 무료 판타지 마을 생성기.

사용 시기

Use whenever your party walks into a new town. The "What can we actually buy here?" question is the #1 GM time-sink.

비교

Old D&D supplements gave static tables. This tool is a live calculator that responds to your size, prosperity, and magic settings.

Enter your values below. Calculations run locally as you type.

작동 방식

Population sets the base scale. Prosperity (×0.5 / ×1 / ×2) and magic level (×0.5 / ×1 / ×2) modify the gold-piece purchase limit and trade counts.

Trade demographics use rough historical fractions of medieval populations — 60% farmers, ~1% blacksmiths, etc.

Use as a starting point for session prep; tweak counts manually for plot-specific NPCs.

자주 묻는 질문

Where do trade ratios come from?

Historical medieval demographic estimates, lightly tuned to feel right for D&D-style settings.

Does this work for sci-fi cities?

Partially. Population scaling is universal; gold-piece limits and trade names are fantasy-coded.

What does the gold-piece purchase limit mean?

It is the value of the most expensive single item a settlement can readily sell, reflecting how much wealth circulates there. A tiny hamlet might cap at a few gold while a large city can supply items worth thousands.

How does prosperity affect the results?

Higher prosperity raises the available cash and purchase limit and tends to support more specialized trades like alchemists and jewelers. A poor settlement of the same population leans heavily toward farmers and basic laborers.

실제 예시

입력

Town (5,000) — standard prosperity — standard magic.

출력

GP limit: 1,000. ~30 blacksmiths, 60 innkeepers, 250 guards.

Town size sets the gold-piece purchase ceiling. Trade ratios follow medieval demographic baselines: ~0.6% blacksmiths, ~1.2% innkeepers, ~4% guards.

흔한 함정

  • GP limits follow D&D 5e DMG ceilings — your game may differ.
  • Trade ratios are pre-industrial — modern/sci-fi settings need adjustment.
  • Doesn't generate named NPCs (use a separate NPC generator).
