Measure the room inside, wall to wall. In an open plan, enter the living area as if it had walls and add the main walkway as a second doorway.

The planner tries every wall, with the sofa against it and floated off it.

How the planner finds a layout

It puts the sofa against each wall in every sensible position, and floated off it with a walkway behind; sets the coffee table in front of it, the chairs at the table’s ends and the TV centered on the wall across; then keeps the arrangements that pass three kinds of check.

  1. Fit. Every piece sits inside the walls without touching another piece, the door’s swing or the landing in front of a second doorway.
  2. Use. Knee room between the sofa and the coffee table, seats close enough to talk, and the TV centered across from the sofa and clear of the window.
  3. Move. A walking path from the door reaches the seats, every chair, the TV and any second doorway, at the width you pick. The planner checks it on a floor grid.

If nothing passes, it draws the closest attempt and tests changes that would work: a shorter sofa, one chair fewer, a narrower TV console or the Minimum setting. Each one is solved again before it is shown.

How it arranges the furniture

  • The TV goes on the wall the sofa faces, centered on the sofa. It can shift up to 18 in to stay on the wall.
  • The coffee table sits centered in front of the sofa; with a sectional, it tucks in beside the chaise.
  • Armchairs face the coffee table from its ends. With the TV turned off, chairs can also sit across from the sofa.
  • The TV console never covers a window: a screen in front of glass fights glare and blocks the light.
  • Viewing distance is measured from your head, about 18 in in front of the sofa back, to a screen about 4 in off the wall.

The TV size it suggests

Each layout lists the standard TV sizes that fill 30 to 40 degrees of your view from the sofa. About 30 degrees suits everyday viewing, and 40, THX’s and LG’s rule, gives a cinema feel. From 10 ft away, 30 degrees takes a 74 in screen, so the suggestions run large; a smaller TV is fine, it just fills less of your view. For your own seat distance, use the TV size calculator.

Start from a measured layout

Every plan on LivingRoomGrid, 14 so far, the ones that pass every check first and the smallest room first. Each one opens in the planner with the room filled in.

What the planner doesn’t check

  • Side tables, lamps, rugs, plants and floor speakers.
  • Outlets, cable runs and where the TV can be mounted.
  • Radiators, vents, fireplaces and window sill heights.
  • Which side the door is hinged on: it assumes the door swings fully into the room.
  • Two sofas facing each other: for that, see two sofas facing each other.

Questions

Is this living room planner free?

Yes. There’s no sign-up, and your room never leaves your browser. Saved plans stay on your device in My living room, and a share link carries the whole plan in its address.

Why does it suggest such a big TV?

The 30 to 40 degree range (40 is THX’s and LG’s rule; 30 is the figure from SMPTE’s old cinema guideline) assumes you want the screen to fill your view. In a 12 ft room you sit about 10 ft from the screen, and 30 degrees from there is a 74 in screen. Many people choose smaller, and that works; the picture just looks smaller from the sofa.

Can I plan an open-plan living area?

Yes. Enter the living zone as if it had walls, then add the main walkway as a second doorway on its open side. The planner keeps a path from the door to it.

Why won’t it put the TV in front of my window?

A screen in front of glass fights glare in the day and blocks the light. If your only TV wall has a window, mount the TV beside it, or turn the TV off in the planner to see seating layouts on their own.
