Measure, check, plan

Litter Mat Size Planner

Try a mat in your measured space, check the doorway and compare two manufacturer-listed sizes.

Measure the exit path

Start with this illustrative plan, then enter your measurements. Calculations stay in this browser; no room data is saved or shared.

1. Measure the space

Measurement units

Measure from the upper-left door hinge. The door swings inward across that corner. For a different hinge, rotate your sketch to match; this tool does not model multiple doors.

Available floor width (cm)Available floor depth (cm)

2. Position the mat

Mat width (cm)Mat depth (cm)Rotate footprint 90 degreesLeft edge position x (cm)Top edge position y (cm)

3. Leave room to use it

Front cleaning / walking access (cm)Clearance on each side (cm)Door swing radius (cm; 0 if no door)Observed cat exit directionAdd a rectangular obstruction (cabinet, toilet, furniture)

4. Check the real room

I measured these dimensions and clearances myselfCat access stays open; walking route is clear of cords, water, children and other pets

Illustrative plan

Your sketch updates as you edit. Teal: item. Dashed: requested access. Red: door sweep. Gray: obstruction. Origin is the upper-left door hinge; front access extends downward.

Text plan: floor 100 × 120 cm; footprint 40 × 60 at (40, 50); front access 10; each side 0; door swing radius 60 cm.

Confirm safe cat access and a route clear of cords, water, children and other pets.

Requested clearance is your measurement, not a universal cat-behavior rule. Test a paper outline and full door travel, include handles, and make sure you can lift, scoop, carry and clean the setup.

Exact size comparison

Confirm your measurements to compare the two recorded variants.

Flooring check: follow your floor maker’s care instructions, lift mats to inspect for trapped moisture, and avoid blocking ventilation or exits.

A size that fits the doorway

A mat can fit a rectangle and still block a door. Measure the swept door area and room to lift the mat; observe the direction your cat exits before buying.

Catit Litter Mat Small #44365: 40 × 60 cm, manufacturer dimensions. Floor compatibility, wet containment and tracking performance are not independently verified.
Catit Litter Mat Large #44366: 60 × 90 cm, manufacturer dimensions. Floor compatibility, wet containment and tracking performance are not independently verified.

Worked example: a 50 × 70 cm unobstructed area fits the 40 × 60 cm Small with 10 cm of front access. The 60 × 90 cm Large fails even before a door sweep is considered. These are illustrative measurements, not a tested apartment.
