Size up each log
Measure length and diameter with a scale stick and logger's tape, then apply the required volume table.
Career profile
Log Grader and Scaler
Log graders and scalers measure and grade logs to work out usable wood and value.
Can you spot the split or rotten core that makes two nearly identical logs different? Sharp eyes and careful measuring count when timber changes hands.
A day in the life
Grade the log by its flaws
You look for knots, splits, decay and bends, then set the grade the grading rules call for.
Keep data with its truckload
Enter species, sizes and flaws on a handheld computer, which can calculate volumes and make the scale ticket.
Mark logs by grade or species
Spray color codes on logs for species or grade, or call grades out to the log marker.

Fit, tradeoffs & changing tools
You might like this if…
- You notice small differences in shape and surface condition.
- You like measurements and orderly records.
- You can accept someone checking your results.
Things to weigh
- Expect outdoor work in changing weather, around hazardous equipment.
- Some jobs run beyond a standard full-time week.
- Your measurements may be repeated by a check scaler. Differences mean revisiting how you measured or judged a defect.
Where AI may help
Handheld software can calculate volumes and prepare tickets. At equipped mills, scanners measure log shape; specialized systems can also build images of the wood inside.
What people still lead
Scalers still supply observations and apply grading rules. Check scalers compare results and help resolve differences in measurement.
What we can’t predict yet
How much hands-on inspection shifts to reviewing scanner results will depend on the mill’s equipment and how well it handles the logs being processed.
Pay in context
Earnings
Use the national figures as a reference, then compare an offer’s hourly rate, expected hours and benefits.
The middle of the pay range
The national median for log graders and scalers was $46,330 a year, or $22.27 an hour. Half earned more and half earned less.
The national spread
The 10th–90th percentile range was $34,950–$62,400 a year, or $16.80–$30.00 an hour. These are points in the wage distribution, not starting and senior pay steps.
Openings despite a decline
Employment is projected to fall 2.2% from 2025 to 2035. About 600 openings a year are projected on average, including replacement needs; that is not a count of jobs available today.
Getting started
Join a scaling bureau as a trainee
- What the route involves
- Learn measurement, grading and safe work routines with a field supervisor who reviews your progress.
- What it can lead to
- Successful training prepares you to work as a scaler and meet the bureau’s accuracy standards.
Build forestry study and experience
- What the route involves
- Combine forestry education with forestry-related work alongside log scalers.
- What it can lead to
- Columbia River Log Scaling & Grading Bureau gives hiring preference to applicants with two years of this combination.
- What to check
- This is an employer preference, not a national degree requirement or a substitute for required licensing.
A high school diploma or equivalent is the usual starting point. Employers differ in how much forestry experience they want before training you.
After entry
Career paths
This starts where the entry routes leave off: early work, growing capability, and advancement or specialization. This path also has a credential or licensing boundary; see the requirements and limits.
Make your measurements dependable
Use feedback to improve your measurements and keep each log’s record attached to the correct load.
Handle harder defects
Build skill with curved, broken or decayed logs. Compare your deductions with check-scale results to see where your estimates diverge.
Move toward check scaling
An advancement target is check scaler or field supervisor: repeat measurements to audit accuracy, explain differences and help other scalers improve.
Where you can work
Sawmill log yard
You work with the mill’s yard crew and other departments. Some positions also include operating a loader or water truck, so the job can mix inspection with equipment work.
- Outdoors
- Physical demands
- Safety-sensitive
Independent scaling bureau
You provide measurements for buyers and sellers without owning the logs. Careful load identification and clear records help both sides use the same account of the wood delivered.
- Outdoors
- Safety-sensitive
Try it
See whether the job clicks before you commit to the path.
Draw two same-size log ends on paper, adding a rotten center to one. Measure both diameters, mark the defect and make a short tally describing the difference. Notice whether you enjoy separating size from usable wood and keeping a clear record.
Stay safe: Keep this a paper exercise; stacked logs and working log yards are not practice spaces.
