Why did the first row change by itself?

The leftover at the far wall was thinner than one-third of a plank. The tool splits that leftover so first and last rows are equal.

Does this work for LVP, laminate, and hardwood?

Yes as a layout and box estimate. Real products differ in click type, underlay, and acclimation. Check the pack.

What is the expansion gap?

A small space at the walls so the floor can move. Ten millimetres is a common starting point. Hide it with skirting.

Are two cut ends counted as one plank?

No. Every visible piece is counted as a plank. That keeps the box number on the safe side.

Can I model an L-shaped room?

Not in this version. Plan the largest rectangle, then add a second run for the alcove and extra waste.

Is the lounge furniture to scale?

It is there for scale and light. Measure real sofas and cabinets separately in the Furniture Layout Planner if clearance is tight.

A square-metre quote will not tell you if the last row is a 40 mm strip along the sofa wall. Set plank size and run direction, then watch the first and last rows balance in a 3D lounge.

Inspect mode paints those edge rows gold and rust. Box counts are conservative. Confirm pack coverage and acclimate the boards on site.

Balance the last row

Change plank size and run direction in a living room. If the last row would be thinner than one-third of a plank, the first row widens so both edges look even.

Last row is 100 mm, wide enough to leave as-is. Inspect mode paints the first row gold and the last row rust.

Underlay matches the room area. Transition length is doorway count times door width. Click-lock waste is conservative: every cut plank is counted as used. Confirm box coverage on the pack.

About Flooring Layout Planner

What this tool does

The Flooring Layout Planner lays planks in a 3D living room so you can compare run direction and stagger before you open boxes.

If the last row would be thinner than one-third of a plank, the first row widens so both edges match. Inspect mode paints those rows gold and rust.

Area calculators hide that skinny last row along the sofa wall. This tool makes that decision visible and counts boxes from the actual plank map.

Underlay matches the room. Transition length is doorway count times door width. Confirm pack coverage on the carton.

How to use it

1Set room width and length in metres or feet.
2Enter plank width, plank length, and planks per box.
3Choose run direction and stagger (1/2, 1/3, or mixed).
4Set an expansion gap at the walls.
5Add doorways if you need transition strip length.
6Switch to Inspect rows to see first and last rows highlighted.
7Note the box count and whether the tool balanced the edges.

Practical tips

Run planks toward the main light or along the longest wall if you want the room to feel longer.
A last row under about one-third of a plank looks cheap. Let the tool split that leftover into both edges.
Leave the expansion gap. Click-lock floors need it, even if the preview looks tight.
Stagger joints so they do not line up across rows. Mixed stagger is closer to a real install.
