Not understanding scale and measuring off reduced prints

Do not scale reduced prints for field dimensions. Use written dimensions, current drawings, approved layout, or verified field measurement.

Stop if

• Is this print full scale, or should I use written dimensions/field measurement only?

Watch out

• Do not pull real dimensions from a reduced or distorted print.

Check

• Check the sheet scale and print size.
• Look for written dimensions first.
• Use full-size/approved drawings when required.
• Field-measure critical conditions.
• Ask before measuring off a reduced PDF/print.
