Most "it doesn't look right" problems in DIY come from measuring and marking, not from the tools. Get this skill solid and every later project goes better.

Reading a tape measure

  • The longest lines are inches; then half, quarter, eighth and sixteenth
  • The metal hook slides slightly on purpose so inside and outside measurements are both accurate
  • Read the tape straight on, not at an angle
  • For inside measurements (inside a window frame), add the case length printed on the tape body

Marking

  • Use a sharp pencil and mark with a small V, the point on the exact spot
  • Measure twice from the same reference edge
  • Write measurements down instead of remembering them

Getting it level

  1. Hold the level against the object or line
  2. Center the bubble between the two lines
  3. For a row of items, draw a light level line first, then measure along it
  4. Floors and ceilings in older homes are rarely level, so things can look crooked even when they're perfect; sometimes matching the ceiling or trim looks better
