Timberlog: Log Scale Calc

Measure logs and sawn timber in seconds. 20+ scaling standards, weight estimates, Excel and PDF reports — the field calculator built for foresters, loggers, and timber buyers.

Timberlog turns diameter and length into precise volume in board feet, cubic feet (CFT), or cubic meters — one-handed, clearly readable in bright sunlight.

MEASURE ANY WAY YOU WORK
• Round timber: log volume from diameter (or circumference) and length
• Sawn lumber (boards, planks, beams): width × thickness × length
• Firewood estimation and stack volume
• Standing tree volume by Noonan (Kershaw)
• Bark thickness deduction and wood weight estimates
