Input options
Enter bed count, room type, clearances, and planning factors. Use metric or imperial inputs; results always show both unit systems.
Example data
These sample values show one possible early-stage setup. Adjust them to match your clinical model and local guidance.
| Scenario | Beds | Type | Min/Bed (m²) | Fixed Add-ons (m²) | Support/Bed (m²) | Circulation (%) | Net→Gross (%) |
|---|---|---|---|---|---|---|---|
| General ICU open bay | 12 | Open bay | 15.0 | 0.0 | 6.0 | 25 | 65 |
| Private rooms | 10 | Single room | 20.0 | 6.0 | 6.5 | 22 | 62 |
| Isolation emphasis | 8 | Isolation | 24.0 | 10.0 | 7.0 | 25 | 60 |
Formula used
-
Patient zone rectangle
Zone length = bed length + head clearance + foot clearance
Zone width = bed width + left clearance + right clearance
Rectangle area = zone length × zone width -
Net area per bed
Net/bed = max(rectangle area, planning minimum) + fixed add-ons
If used: Net/bed = Net/bed × (1 + bed/bay add-on %) -
Net total with circulation
Patient net total = Net/bed × number of beds
Support total = support allowance/bed × number of beds
Net with circulation = (patient net total + support total) × (1 + circulation %) -
Gross total
Gross total = Net with circulation ÷ (net-to-gross %)
These equations provide a structured estimate for planning. Always validate final layouts with clinical operations, infection control, and applicable health facility guidelines.
How to use this calculator
- Select metric or imperial units for your inputs.
- Enter the number of ICU beds and choose a room type.
- Set bed clearances to reflect equipment and staff access.
- Use planning minimums to enforce practical per-bed targets.
- Add fixed room components for toilets or isolation anterooms.
- Include support and circulation to avoid under-sizing.
- Review net and gross totals, then export CSV or PDF.
