Projection Area vs Unfolded Area: How to Calculate Cabinets Without Wasting Money

When ordering custom wardrobes, cabinets and storage systems, two pricing methods always confuse buyers: projection area and unfolded area. Many homeowners end up overpaying due to miscalculations or hidden charges. We break down the two calculation standards, compare their cost pros and cons, and teach you how to avoid extra fees during customization.

1. What Is Projection Area Pricing?

Projection area is the most mainstream pricing model for custom furniture. It calculates cost based on the cabinet’s outer width multiplied by its height, ignoring internal layers, drawers and partitions.

Core Advantages

The quotation is straightforward and easy to compare across suppliers. Standard accessories like fixed shelves come included without extra fees, ideal for simple open wardrobes with few drawers.

Hidden Drawbacks

High-volume add-ons such as multi-layer drawers, pull-out baskets, glass doors and special partitions will trigger surcharges. Complex custom layouts can push up the final bill drastically.

Result: Projection area suits simple, low-accessory cabinet designs.

2. What Is Unfolded Area Pricing?

Unfolded area counts every single wood panel used in the cabinet separately. Every vertical board, horizontal shelf, backboard and divider is measured and charged individually.

Core Advantages

No hidden extra fees for internal structures. If you need abundant drawers, multi-layer storage and customized internal divisions, the total cost is more transparent and predictable.

Hidden Drawbacks

Quotation reading is complicated. Basic empty wardrobes with minimal internal boards often cost more than projection area pricing, and backboard, edge banding may be listed as separate charges.

Result: Unfolded area works best for highly customized cabinets with lots of internal storage components.

3. Real Cost Comparison Test: Same Wardrobe, Two Calculations

We priced a standard 2.4m*2.6m bedroom wardrobe with both methods to show the cost gap.

Scenario A: Simple wardrobe with 2 drawers only

Projection area billing came out 18% cheaper, as basic shelves were fully covered in the unit price.

Scenario B: Complex wardrobe with 8 drawers, pull-out mirrors and storage baskets

Unfolded area billing saved nearly 25%, avoiding heavy drawer surcharges under projection area rules.

4. Money-Saving Rules to Avoid Wasted Budget

Choose projection area pricing if:

You need basic wardrobes, TV cabinets, entry storage with few drawers and simple internal layout; you want quick, easy price comparison between factories.

Choose unfolded area pricing if:

You plan elaborate kitchen cabinets, walk-in closets, multi-functional storage with dozens of drawers, pull-out accessories and custom partitions.

Universal Cost Prevention Tips

Always confirm all included accessories in the contract; clarify extra charge standards for drawers, glass panels, special hardware and top cabinets before signing; ask for a full breakdown sheet of every panel or add-on fee.

Final Selection Guide

Pick projection area for simple, basic cabinets to cut overall costs. Opt for unfolded area when you require heavy internal customization to skip overpriced accessory surcharges. Clear pricing breakdowns are the key to avoiding unnecessary extra spending on whole-house customization.

Industry Truth

Neither pricing method is inherently cheaper. The better option depends entirely on your cabinet’s internal complexity.

Projection area offers budget savings for minimalist, simple storage furniture.

Unfolded area delivers fairer pricing for heavily customized cabinets with rich internal fittings.

Never judge quotations by unit price alone. Always match the calculation rule to your storage demands to prevent hidden overspending.
