A hygrometer beside an acoustic guitar in a room

Read your room's humidity off any hygrometer, log it here, and watch the trend. The tool tells you if you're in the safe band and nudges you when winter air starts drying things out.

Roady Hint
Guitars are happiest between 45% and 55% relative humidity. Below ~40% is the one to watch — dry air shrinks the wood and can crack a top or lift fret ends. Above ~60% swells things up: higher action, a duller tone. The silent troublemaker is winter: indoor heating can quietly drag a room down to 25–30% without you noticing, which is exactly what the trend below is here to catch.

Good to Know

Humidity Tracker questions, answered

What humidity should I keep my guitar at?

Aim for 45–55% relative humidity. Roughly 40–60% is tolerable, but under 40% risks cracks, sunken tops and sharp fret ends, while over 60% brings swelling, higher action and a duller tone. Solid-wood acoustics are the most sensitive.

Where do the readings come from?

You enter them yourself from a hygrometer in the room — a cheap one works fine. Nothing is measured automatically and nothing leaves your browser. The tracker just stores your readings and shows you the trend.

Does it treat acoustics and electrics differently?

The target is the same for both. Solid-wood acoustics react fastest, so they're the ones to watch. Solidbody electrics are tougher, but their necks and fretboards still move with humidity, so 45–55% is a good goal for everything on the wall.

Does it remember my readings?

Yes. Every reading is saved privately in your own browser, so your history and trend are waiting when you come back. No account, nothing uploaded.
