Drop Count Estimator
Work-area outlet, drop, and patch-panel planning counts from floor area — TIA planning rules of thumb, stated as such.
| Work areas | 160 |
| Work-area drops | 320 |
| WAPs (×2 drops each) | 8 (16 drops) |
| Cable runs incl. 20% growth | 404 |
| 48-port patch panels | 9 |
| Rack space (panels + management + actives allowance) | ≈ 33 RU → 2 racks |
Planning numbers, not a design — real counts come from furniture plans, device schedules, and an RF survey.
Where the math comes from.
What this estimates — and what it doesn’t
This is a planning estimator: it converts usable floor area into work-area counts, drops, cable runs, patch-panel positions, and a first-pass telecom-room rack count using customary planning ratios. It is the number you take into early budgeting and TR sizing conversations — not a design. The design comes from actual furniture plans, device schedules, and coverage modeling.
The ratios behind it
Defaults: one work area per 100–150 usable square feet (offices), two drops per work area (TIA-568 recommends a minimum of two outlets per work area), one wireless access point per ~2,500 sq ft of typical office space (real WAP counts come from an RF design), and 48-port patch panels with a growth allowance you control. Every ratio is editable — density varies wildly between an open-plan office, a clinic, and a warehouse.
From drops to rack units
The tool rolls cable counts into patch-panel positions and adds wire management to sketch the TR’s rack space. Use it to sanity-check whether the architect’s proposed telecom room can ever work — the cheapest time to win that argument is before the floor plan freezes (TIA-569 sizing guidance is the standard to cite when you do).
Asked about this one.
The calculator sketches it. The design defends it.
When the number has to survive plan review, bidding, and closeout testing — that's RCDD design work, and it's what we do.
