10 Reasons Your Stock Picking Speed Isn’t Working

In the world of logistics and e-commerce, speed isn't just a "nice to have": it is the heartbeat of your business. If your pickers are taking too long to find, grab, and move items, your entire operation starts to lag. You face missed shipping windows, unhappy customers, and rising labour costs.

Often, when a warehouse manager notices a dip in efficiency, the first instinct is to tell the staff to "work faster." But usually, the problem isn't the person; it’s the environment. Your shelving, your layout, and your organisation are likely working against your team.

If you feel like your picking rates have plateaued, here are 10 common reasons why your stock picking speed isn’t working and, more importantly, how you can fix it.

1. Your Travel Distances Are Too Long

The single biggest "time thief" in any warehouse is travel time. Statistics suggest that in a poorly designed warehouse, pickers can spend up to 60% of their time simply walking from one location to another. If your fast-moving items are tucked away at the back of the building, you are paying your staff to go for a long walk rather than to pick stock.

The Fix: You need to implement a "heat map" of your inventory. Place your most popular items (your "A" stock) nearest to the packing stations. By reducing the physical distance a picker has to travel for the majority of orders, you instantly boost your picking rates. Take a look at your current layout and see where you can trim the fat.

2. You Aren't Using the "Golden Zone"

Every shelving unit has a "Golden Zone." This is the area between a picker’s waist and shoulders. Items stored here can be picked instantly without the need for stretching, bending, or using ladders. If your high-demand items are on the bottom shelf or the very top, every pick takes five seconds longer than it should. Multiply that by 500 picks a day, and you’ve lost nearly an hour of productivity.

The Fix: Slot your most frequently picked items in the Golden Zone. Reserve the very top and bottom shelves for bulk storage or slow-moving items. Using versatile shelving that allows for easy shelf adjustment is key here, as your "Golden Zone" might change depending on the size of the products you carry.

3. Your Shelving Doesn't Match Your Product Size

Are you storing small electronics on deep, heavy-duty industrial pallet racks? Or perhaps you’re trying to cram large boxes into narrow shelving? When shelving isn't sized correctly for the product, pickers struggle to see what’s at the back, or they have to move three things to get to the one they actually need.

The Fix: Match the shelving to the stock. For smaller items and high-density picking, our Profile Shelving is a game-changer. It offers a slim profile that maximises every millimetre of space, ensuring items are visible and easy to grab. If you’re dealing with heavier goods that still require quick hand-picking, something like the Speedrax range provides the stability of industrial storage with the accessibility of a picking shelf.

4. Poor Lighting Leading to "Search Time"

It sounds simple, but you’d be surprised how many warehouses operate in a permanent state of "dim." If a picker has to squint to read a SKU code or use their phone torch to see into the back of a shelf, your picking speed will plummet. Poor lighting doesn't just slow people down; it leads to mis-picks, which are even more expensive to fix.

The Fix: Audit your lighting. Ensure that light fixtures are positioned over the aisles, not directly over the top of the shelving units (which creates shadows). If you’re using tall racks, like our 2m and above shelving, you might need to look at vertical light distribution to ensure the bottom levels are just as visible as the top.

5. Congested Aisles and One-Way Traffic Issues

If your pickers are constantly having to move out of each other's way, or if a single trolley blocks an entire aisle, you have a traffic problem. "Deadhead" time: where a picker is stuck waiting for someone else to move: is a complete waste of resources.

The Fix: Review your aisle widths. While it’s tempting to pack shelves as close together as possible to save space, you need enough room for "two-way" human traffic at the very least. If space is tight, implement a one-way picking route. This keeps the flow moving in a single direction and prevents the "bottleneck" effect.

6. You’re Ignoring Vertical Space

Are you out of floor space? Many businesses stop picking efficiently because they’ve cluttered the floor with "temporary" pallets. This creates an obstacle course for your team. If you are only picking at ground level, you are ignoring half of your warehouse's potential.

The Fix: Go up. By using 1800mm shelving or even taller units, you can clear the floor and organise stock vertically. Just remember: keep the "picks" at a reachable height and use the higher levels for replenishment stock. This keeps the floor clear for fast movement.

7. Inadequate Labelling and Signage

If a new hire can’t find a product within 30 seconds without asking for help, your signage has failed. Relying on "tribal knowledge": where only the person who has worked there for ten years knows where things are: is a recipe for disaster.

The Fix: Implement a clear, alpha-numeric coordinate system for every shelf and bin. Use large, high-contrast signs at the end of every aisle. 

8. The Packing Station Bottleneck

Sometimes, picking speed isn’t actually about the picking: it’s about the drop-off. If a picker finishes their circuit but has nowhere to put the items because the packing area is a mess, they stop moving. A cluttered workspace slows the transition from "picked" to "shipped."

The Fix: Professionalise your packing area. Using dedicated workbenches gives your team a clear, organised space to process orders. When there is a designated spot for tape, boxes, and labels, the hand-off from the picker to the packer becomes seamless.

9. Mixing Multiple SKUs in One Bin

In an effort to save space, it’s common to see three or four similar-looking products tossed into the same picking bin. This is a nightmare for speed. The picker has to stop, pick up each item, check the barcode, and put the wrong ones back.

The Fix: One SKU, one location. It’s a simple rule, but it’s effective. If you have limited space, use shelf dividers or smaller bins within your industrial storage units to keep items segregated. It’s better to have 20 small, organised slots than 5 large, messy ones.

10. Using the Wrong Type of Storage for the Job

Every industry has specific needs. If you’re in the food sector and using standard painted steel that’s hard to clean, or if you’re an office using heavy warehouse racking for files, you’re using the wrong tool for the job. This leads to awkward handling and slower movement.

The Fix: Use specialised equipment where necessary. For example, catering and kitchen shelving is designed for hygiene and airflow, which actually makes picking food items faster because you aren't fighting with rust or grime. 

It’s Time to Reclaim Your Speed

Improving your picking speed isn't about working harder; it’s about working smarter. By looking at your layout, upgrading your Speedrax heavy duty storage shelves, and ensuring your team has the right workbenches to finish the job, you can transform your warehouse from a bottleneck into a high-speed engine.

Think about your warehouse right now. Where is the "clutter"? Where are the "long walks"? Identifying just two or three of these issues and fixing them this week could increase your output by 10-15% almost overnight.
