Planet Atmosphere Scale Heights 3D Explorer vs Karman Line & Atmosphere Layers 3D Explorer
freetoolonline.com editorial team
Both pages teach a real atmosphere figure in one page load - 0 MB installed, USD 0, no account. The Planet Atmosphere Scale Heights 3D Explorer compares how fast pressure drops with altitude across FIVE different worlds under one shared formula; the Karman Line & Atmosphere Layers 3D Explorer zooms into ONE world, Earth, and pins its own named layers and space-boundary conventions to real altitudes.
The numbers side by side
| Aspect | Scale Heights Explorer | Karman Line Explorer |
|---|---|---|
| Install size | 0 MB - runs in the browser | 0 MB - runs in the browser |
| Price | USD 0 | USD 0 |
| Key figure | Earth's own scale height: 8.5 km (NASA NSSDCA) | Karman line: 100 km (FAI, 1960) |
| Governing relationship | pressure over surface pressure = e^(-altitude/scale height) | Four named layers (troposphere, stratosphere, mesosphere, thermosphere) plus three real boundary markers |
| What it varies | Altitude (0-90 km) across 5 worlds: Venus, Earth, Mars, Jupiter, Titan | Altitude (0-650 km) on Earth only, with 5 jump buttons |
| What it answers | How much of each world's own surface pressure survives at a given height | How far a given altitude sits from the Karman line, the US boundary, and the ISS orbit |
Where the Scale Heights Explorer wins
The Scale Heights Explorer wins when the question is a world-to-world comparison - it is the only page on the site that puts Venus, Earth, Mars, Jupiter, and Titan's pressure decay side by side under one shared formula.
Where the Karman Line Explorer wins
The Karman Line Explorer wins when the question is Earth-specific - it names Earth's own four real atmosphere layers and pins the ISS orbit, meteor ablation, and aurora zone to their own real altitudes, none of which the scale-height comparison shows at all.
A reasonable rule
As a reasonable rule, use the Scale Heights Explorer first to see how different worlds compare to each other, then use the Karman Line Explorer to see where Earth's own named layers and real objects sit within Earth's own atmosphere.

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
