TL;DR: This fantasy calculator estimates a broomstick’s approximate flight range (km) from three story-friendly inputs: broom efficiency, rider weight, and a temporary magical boost. Use it for tabletop RPGs, fiction planning, or worldbuilding—not real aviation.
Flight range is the distance your broom can reasonably cover before its enchantment “taps out” (or before the rider needs to stop for safety, focus, or a recharge ritual). Because broomsticks in fantasy settings are powered by magic rather than fuel, there’s no single real-world physics model to copy. Instead, this calculator provides a consistent narrative baseline that reacts sensibly to the three inputs you can control at the table:
The result is best used as a guideline for pacing travel scenes, comparing broom models, pricing courier contracts, or deciding whether a “one-hop” flight is plausible without a rest stop.
The calculator follows a simple logic:
One common representation of that idea is:
Where:
Your site’s internal implementation may differ slightly, but the interpretation stays consistent: higher efficiency and boost increase range, while higher weight decreases range.
Use efficiency as a single stat that wraps craftsmanship, enchantment stability, and how well the broom converts magic into sustained flight.
Enter the total load: rider body weight + clothing + pack + any carried items. If multiple riders share a broom, add them together (or treat a sidecar/basket as additional “gear weight”).
Boost is temporary and situational—something that makes this particular trip better than normal.
The output is an estimated maximum comfortable range in kilometers. In most stories and campaigns, you can treat that number as a “one-leg distance” before one of the following becomes likely:
If you want a more conservative travel plan, take 80–90% of the shown range as a “no-drama” distance, reserving the last 10–20% for emergencies or heroic pushes.
Scenario: A courier takes a dependable mid-tier broom across the marshlands with a modest ritual boost.
Using the illustrative formula above:
Interpretation: Plan for a ~40 km one-leg flight before stopping at a watchtower, roadside shrine, or safe clearing to reset wards and rest.
| Change | What it represents in-world | Typical effect on range |
|---|---|---|
| Increase efficiency | Better materials, stronger runes, cleaner spellwork | Range increases roughly proportionally |
| Increase boost % | Temporary amplification (ritual/potion/conditions) | Range increases by a multiplier (often noticeable) |
| Increase weight | Heavier rider, armor, cargo, extra passenger | Range decreases (sometimes sharply at high loads) |
| Same numbers, harsher conditions | Fog, cold, ward interference, hostile airspace | Treat as lower boost or lower efficiency |
The calculator output is in kilometers. To convert to miles, multiply km by 0.621 (or divide by 1.609).
Add everyone’s weight (plus shared gear) and enter the total as rider weight. If it’s cramped or unstable, reduce efficiency by 1–2 points to reflect poor handling.
Many campaigns treat student models as 4–6. Older or poorly maintained brooms might be 2–4, while competitive models start around 7+.
Either lower efficiency (the broom struggles) or lower boost (conditions suppress magic). For severe interference, do both.
This tool estimates distance, not speed. If you have a separate speed rule, you can compute time as time = distance / speed (in consistent units).
