Why there's no automatic collision check, and what that means

Wall thickness, which way a door swings, low walls under windows, outlet locations, a floor-heating distribution box — real spaces are full of constraints that never show up on a plan. Since this tool simply overlays furniture as rectangles, it does not automatically detect furniture sinking into walls or overlapping other pieces. Always double-check against the floor plan and the actual space to make sure walkways are wide enough and that doors or sliding doors won't collide with anything when they swing open.

Reading traffic flow and "breathing room"

Whether you need space behind a sofa or beside a bed for cleaning or airing out bedding really comes down to your lifestyle. The tool will happily let you pack things down to the centimeter, but in real life it pays to deliberately leave a minimum working margin — you'll regret it less. The areas in front of and behind the kitchen counter, in front of the sink, and along the entryway path are especially worth prioritizing for extra width.

Approximating round tables and cylinders

The tool is built around representing furniture in 2D as rectangular footprints. For a round table or a circular rug, the usual approach is to enter the diameter as both the "width" and the "depth", approximating it as its bounding square. Keep in mind that the footprint with chairs pulled out is larger than the diameter alone, so leave extra clearance around it.

Natural light and sightlines need more than 2D

How comfortable it feels to orient a TV or desk a certain way, or which end of the bed the headboard sits at, depends heavily on the relationship to windows, the balcony, and neighboring units. Even when the dimensions line up perfectly on a flat plan, it's common to want to change the layout once you compare it against the actual window and door positions. Where possible, cross-check with on-site photos or a virtual walkthrough.

Save and compare multiple layouts

Saving several named layouts — say, "Plan A: storage-focused" versus "Plan B: open living room" — makes it much easier to talk things over with family or a partner. Save behavior can vary by environment on both the web and app versions, so for any layout you really care about, consider backing it up the same way you would with the sample data.

Don't lock in your first idea

Traffic flow and storage space tend to trade off against each other, so settling on the very first layout you come up with often leaves you with a skewed result. Try saving multiple versions built around different priorities — bed-first, storage-first, guest-friendly — and comparing them; it makes it much clearer what actually matters most to you.
