Installing more racks does not always mean getting more storage space.

A good warehouse rack layout should consider the products being stored, rack type, aisle width, loading method, warehouse height and daily workflow before installation begins.
Whether you are planning a small storeroom or a larger warehouse in Kuala Lumpur, Selangor, Penang or other parts of Malaysia, choosing the correct racking system and layout can help you maximise storage space while keeping stock easier to access and manage.

At Rack Zone, we provide solutions including boltless rack, LS500 long span rack, heavy duty rack, warehouse rack, pallet racking and mezzanine floor systems for different storage requirements.

1. Understand What You Are Storing First
Before deciding how many racks can fit into your warehouse, start with the products.
Ask yourself:

For example: Small Cartons & General Stock
A boltless rack may be suitable for manually handled cartons, office stock, retail inventory and general storeroom items.
Larger or Heavier Hand-Loaded Items
An LS500 long span rack may be more suitable when the products are larger, wider or heavier but still need to be manually picked.
Palletised Goods
For goods stored on pallets and handled using forklifts or reach trucks, a heavy duty pallet racking system is normally more appropriate.
Choosing the rack based on the actual products helps prevent both wasted space and unsuitable storage.

2. Measure the Warehouse Properly
Accurate measurements are extremely important before planning a warehouse layout.
Measure the:

Do not calculate rack space using only the total floor area.
A warehouse may look large on paper, but columns, doors, walkways and operating areas can reduce the actual usable storage space.

3. Make Use of Vertical Space
One of the biggest advantages of warehouse racking is the ability to use vertical space.
Instead of keeping cartons or stock only on the floor, shelving allows products to be stored upwards.
For manually picked products, boltless or long span racks can provide several adjustable shelf levels.
For larger warehouses with palletised goods, taller pallet racking may significantly increase storage capacity.
However, the rack height should always be suitable for:

The tallest rack is not automatically the best rack. The goal is to create usable storage space.

4. Plan Enough Aisle Space
A common mistake is trying to fit too many racks into one area.
If the aisles become too narrow, staff may struggle to move cartons, trolleys or equipment through the warehouse.
For pallet racking, aisle planning becomes even more important because forklifts or reach trucks need sufficient space to turn and retrieve pallets.
The required aisle width depends on:

Good warehouse planning should balance storage capacity and accessibility.
More racks are not useful if staff cannot access the products efficiently.

5. Consider Your Daily Warehouse Workflow
A warehouse layout should support the way your team actually works.
Think about how goods move through the warehouse:
Receiving → Storage → Picking → Packing → Dispatch
Frequently picked products can be stored closer to the picking or packing area.
Slow-moving inventory may be placed further inside the warehouse.
For businesses with many SKUs, products can also be organised according to:
Product category

For example, our pigeon hole boltless rack solution is particularly useful for fashion and e-commerce businesses that need to separate many different SKUs into individual compartments.
A good rack layout can reduce unnecessary walking and searching during daily operations.

6. Choose the Correct Rack for Each Storage Area
A warehouse does not necessarily need to use only one type of rack.
Different areas can use different systems.
Boltless Rack
Suitable for:

Suitable for:

LS500 Long Span Rack
Suitable for:

Suitable for:

A mezzanine floor may be considered when the warehouse has sufficient vertical height and additional floor space is required for storage, office areas or other permitted uses.
Using the correct rack in each zone can make the warehouse more practical and efficient.

7. Check the Loading Capacity
Loading capacity is one of the most important factors when choosing any warehouse rack.
Do not select a rack based only on its appearance or dimensions.
The supplier should understand:

For shelving systems, loading capacity is commonly based on Uniformly Distributed Load (UDL).
This means the weight should be spread evenly across the shelf instead of concentrated at one point.
For example, several cartons spread across the shelf create a different loading condition compared with placing one very heavy machine in the centre.
Always provide the maximum expected load when requesting a quotation.

8. Leave Room for Future Expansion
Your current warehouse requirements may not be the same one or two years from now.
Before finalising the rack layout, consider whether your business may need:

A modular rack system gives businesses more flexibility when storage requirements change.
Boltless and long span racks can also be dismantled and reconfigured, making them useful for businesses that may rearrange or relocate their warehouse in the future.

9. Do Not Block Important Access Areas
Storage racks should not obstruct areas that need to remain accessible.
When planning your layout, check the positions of:

For larger warehouse projects, a site measurement is strongly recommended before installation.
This allows the available space and site restrictions to be identified before the racks are delivered.

10. Think About Installation Before Ordering
A warehouse rack quotation should not only state the product price.
For larger installations, customers should also confirm:

Planning these details earlier can reduce delays during delivery and installation.
Why a Proper Warehouse Rack Layout Matters

A well-planned warehouse racking system can help a business:
✅ Maximise available floor and vertical space
✅ Improve stock organisation
✅ Reduce clutter
✅ Make products easier to locate
✅ Improve picking efficiency
✅ Create clearer warehouse aisles
✅ Prepare for future business growth

The objective should not simply be to install the maximum number of racks.
The better approach is to create a warehouse where storage capacity, accessibility and daily operations work together.

Frequently Asked Questions About Warehouse Rack Planning

What information should I provide before requesting a warehouse rack quotation?
Prepare your warehouse dimensions, installation location, product dimensions, estimated weight, quantity, number of SKUs and whether the products will be manually handled or stored on pallets.
Photos or a floor plan are also useful.

Which rack is suitable for a small warehouse?
For manually handled cartons and general inventory, boltless racks are often a practical choice.
If the products are larger or heavier, LS500 long span racks may be more suitable.

When should I use pallet racking?
Pallet racking is normally suitable when products are stored on pallets and handled with forklifts, reach trucks or other warehouse equipment.

Can I combine different types of racks in one warehouse?
Yes. Many warehouses benefit from using different systems for different products.
For example, pallet racking may be used for bulk stock while boltless or pigeon hole racks are used for individual item picking.

What is the best rack for many different SKUs?
For smaller manually picked products, a pigeon hole rack can help separate different SKUs, sizes, colours or product categories into individual compartments.

Can warehouse racks be moved later?
Many boltless and long span rack systems can be dismantled and reinstalled. However, any new configuration should still be suitable for the rack specification and loading requirements.

Why is aisle width important?
Sufficient aisle space allows staff, trolleys and handling equipment to move safely and efficiently between racks.
For pallet racking, the required aisle depends heavily on the forklift or reach truck being used.

Should I measure my warehouse before buying racks?
Yes. Accurate measurements reduce the risk of ordering racks that are too tall, deep or wide for the available space.
For larger projects, a professional site measurement is recommended.
