Room Fit Planner

A transparent first-pass calculator for one common living-room arrangement. It tells you whether the dimensions fit your own clearance target; it does not certify accessibility, compliance or comfort.

Wall to wall at the narrowest usable point
Sofa wall to media wall
Use the widest external dimension
Include recline or loose-back overhang
Enter 0 for a wall-mounted screen without a unit
Enter 0 to remove the coffee table
This is your design target, not a legal rule

Calculated result

First-pass fit check

Clear gap per route segment—
Side allowance beside sofa—
Estimated open floor area—

Model: sofa, optional coffee table and a full-width media zone arranged along the room length. It ignores doors, radiators, bay windows, chair movement, circulation around corners and accessibility needs. Confirm the result on a scaled plan and with the actual product dimensions.

How to use the result

  1. Test the narrowest real dimension. Skirting, chimney breasts, radiator valves and door swings reduce the rectangle you can actually furnish.
  2. Choose the target deliberately. Increase it for a main route, mobility equipment, frequent passing or doors that open into the space. The tool does not prescribe a universal number.
  3. Mark the result on the floor. Painter's tape or paper footprints reveal corner conflicts and sight lines that a single depth calculation cannot see.
  4. Check every moving state. Test recliners, drawers, footstools, extendable tables and the route when someone is seated.
Why the clearance is user-definedThe UK's Nationally Described Space Standard concerns the gross internal area and selected dimensions of new dwellings; it is not a furniture-layout rule for an existing living room. Approved Document M has a regulatory scope that also cannot be converted into one universal furniture gap. Roomology therefore shows the assumption instead of presenting an arbitrary preference as compliance.
