How It Works

Transition strips bridge the gap between two flooring types. T-molding joins same-height floors, reducers join different heights, and thresholds finish at doorways.

The Formula

Strips = CEIL(Total Linear Inches / Strip Length)

Variables

  • T-Molding — For same-height floors (e.g., laminate to laminate)
  • Reducer — For different heights (e.g., hardwood to tile)
  • Threshold — For doorway edges or floor-to-carpet transitions

Example

3 transitions at 36" each = 108" total. With 36" strips, need 3 strips.

Tips

  • Match the transition strip to your flooring color — most manufacturers sell matching strips.
  • T-molding requires a channel/track screwed to the subfloor.
  • Reducers hide height differences of up to 3/8".
  • Use a threshold at exterior doors for weather sealing.
