pick density calculator
Pick density calculator
Estimate total picking hours based on orders, SKUs per order, and pick speed.
Summary
- Calculates labor hours needed for picking
- Uses SKUs per order and pick speed
- Useful for staffing and wave planning
- Helps compare layouts or process changes
Definitions
- Pick speed
- How many SKUs/items a picker can pick per hour.
- SKUs per order
- Average number of items per order.
- Pick density
- Total pick workload per wave or shift.

Estimated pick hours
13.3 hrs
Total SKUs: 1600
Hours per picker: 1.67
Pick hours vs SKUs/order
If SKU density changes
Worked example
Inputs
- Orders
- 500
- SKUs per order
- 3.2
- Pick speed
- 120 SKUs/hour
Outputs
- Total SKUs
- ≈ 1,600
- Pick hours needed
- ≈ 13.3 hours
If pick hours exceed available labor, reduce wave size, increase pick speed, or add pickers.
Benchmarks / ranges
These are conservative ranges. Your results depend on density, stops, traffic, and service type.
- Pick speed (manual)80–140 SKUs/hourDepends on layout and travel time.
- SKUs per order1–6Higher SKU count increases complexity.
- Wave size100–800 ordersTune to staffing and dock capacity.
What to do next
- If pick hours are too high, split into smaller waves.
- Improve slotting or layout to raise pick speed.
- Track actual pick speed weekly and update assumptions.
Use Lynxo to run this in real life
Lynxo is delivery management software: dispatch + driver app + live tracking + proof of delivery + reporting.
- Plan routes and assign runs in a dispatch dashboard
- Send live ETA links so customers/sites are ready
- Use a driver app for stop-by-stop execution and exceptions
- Capture proof of delivery (photos, signatures, timestamps) per stop
Where this helps
- Warehouse labor planning
- Order wave sizing
- Layout or process change ROI
FAQs
Should I include packing time here?
No. Add packing as a separate step or include it in pick speed if teams are combined.
What if SKU counts vary a lot?
Use a weighted average (or split fast/slow orders into separate waves).
How do I improve pick speed?
Better slotting, clear labels, and fewer travel steps usually help most.
