РусскийOver 30 timber calculators in one app
One app instead of tables, paper and spreadsheets. Volume, weight, sawing, moisture and drying — in metric and imperial units.
Everything you can calculate
Enter timber length in mm, cm or m — whatever you're used to.
Logs

- Scaling by 22 methods used worldwide
- Log weight and weight from dimensions
- Log volume from weight
Trees and stands
- Standing tree volumeDoyle, Scribner, International, Petráš and Pajtík
- Tree volume from stump diameter
- Tree agegrowth factor by species

Moisture, drying and conversions
- Wood moisture content
- Absolute air humidity
- Wood drying timeair, solar, kiln, condensation, vacuum
- Unit converterslength, area, volume, weight
22 methods, 134 volume tables
Huber in Ireland and elsewhere in Europe, Hoppus historically in the United Kingdom and Ireland, Scribner and Doyle for North America, JAS or Guo Biao for other markets. Choose the method in the settings and the app uses it everywhere.
Your colleague got a different number? Almost always it's a different scaling rule — the difference between methods is real, not an error. Compare the method, decimal places and rounding in the settings.
- Without signal tooThe log volume and lumber volume calculators always work offline, even without a subscription.
- Favourites on topChoose which calculators you see and in what order.
- Species dataThe other calculators use species data we have been building for years — that's why they need a connection.
- Right in your recordsThe tally recorder calculates the volume of every piece you enter and keeps a running total.

Frequently asked questions
Do I need internet or registration for the calculators?
No. The calculators in the app work right after installing it from Google Play, with no registration and no signal needed.
Which standards do the calculators use for log volume?
22 methods – for example Huber, Smalian, Doyle, Scribner and International ¼″. You choose the method in settings; the result is in m³ or board feet.
Does the app also calculate timber weight?
Yes. From volume, species and moisture it calculates weight, so you can estimate a truck load or a price per tonne.
