Understanding Space Efficiency
Efficiency Formula
Efficiency (%) = (Occupied Area ÷ Total Room Area) × 100
Where Occupied Area is the sum of all placed furniture footprints
Standard Furniture Dimensions
| Furniture Type | Typical Width | Typical Length | Category |
|---|---|---|---|
| Queen Bed | 5 ft (60") | 6.67 ft (80") | Bedroom |
| King Bed | 6.33 ft (76") | 6.67 ft (80") | Bedroom |
| 3-Seater Sofa | 7 ft (84") | 3 ft (36") | Living Room |
| Dining Table (6-seat) | 6 ft (72") | 3 ft (36") | Dining |
| Office Desk | 5 ft (60") | 2.5 ft (30") | Office |
| Wardrobe | 4 ft (48") | 2 ft (24") | Bedroom |
Walking Space Guidelines
Absolute minimum for single-person passage. Suitable for tight spaces like closets or small bedrooms.
Recommended for most residential spaces. Allows comfortable movement and furniture access.
Ideal for high-traffic areas, commercial spaces, or accessibility requirements.
Room Planning Tips
- Start with Large Items: Place beds, sofas, and tables first, then add smaller pieces
- Consider Traffic Flow: Ensure clear paths between doorways and frequently used areas
- Leave Breathing Room: Don't push all furniture against walls; floating pieces can improve flow
- Think Functionally: Group furniture by activity zones (sleeping, working, relaxing)
- Account for Doors: Ensure furniture doesn't block door swings or cabinet openings
- Use Vertical Space: Tall furniture can maximize storage without increasing footprint
- Test Before Buying: Use this calculator to verify new furniture will fit before purchasing
- Consider Proportions: Match furniture scale to room size for balanced aesthetics

Frequently Asked Questions
What is a good efficiency score for a room?
For residential spaces, 40-60% is generally optimal. This provides adequate furniture while maintaining comfortable walking space. Commercial spaces may target 50-70% depending on function.
How much walking space should I leave?
Minimum 2 feet for tight spaces, 3 feet for comfortable residential use, and 4+ feet for high-traffic or accessible areas. The calculator helps you visualize these clearances.
Can I use this for commercial spaces?
Yes! The calculator works for any interior space. For commercial use, consider local building codes for accessibility, egress, and occupancy requirements.
What if my furniture doesn't fit?
The calculator will show overflow items that couldn't be placed. Try enabling rotation, reducing walking space slightly, or removing/resizing furniture items.
How accurate is the placement algorithm?
The algorithm uses grid-based placement with collision detection. While it provides good initial layouts, you may want to adjust positions based on windows, doors, and personal preferences.
Can I save my layouts?
Yes! Use the "Save to History" button to store calculations in your browser. You can also export detailed reports as text files.
