The area calculation for whole house customization mainly adopts the following three methods, among which the projected area is the most commonly used and recommended calculation method:

1、 Main calculation methods and characteristics

Projection area calculation method

Formula: Length (meters) x Height (meters) x Unit Price (yuan/square meter)+Additional Configuration Cost

Characteristics:

Simple and intuitive calculation, widely adopted by merchants. For example, a wardrobe that is 1.5 meters wide and 2.2 meters high has a projected area of 3.3 square meters.

Usually includes standard configurations (such as boards, basic hardware), but additional fees are required for parts that exceed the standard (such as pants racks, storage baskets).

The depth of the cabinet within the standard range (such as 55-60cm for wardrobes and 35-40cm for TV cabinets) does not affect the price and is suitable for designs with more layers.

Expand the area calculation method

Formula: Total area of each panel (panel+back panel+side panel, etc.)+accessory cost

Characteristics:

Accurate but complex, requiring separate calculation of all panels, suitable for users with high requirements for structural details.

There is a risk of price opacity, and when modifying the plan, it is necessary to recalculate, which may result in additional costs.

Linear meter pricing (cabinet specific)

Formula: Unit price per linear meter x number of linear meters+additional configuration cost

Characteristics:

Mostly used for cabinets, including 1-meter hanging cabinets, 1-meter floor cabinets, and 1-meter countertops.

Special structures such as corners may lead to hidden price increases, and we need to be vigilant about price differences.

2、 Choose Suggestions

Recommended projection area: Suitable for ordinary consumers, easy to budget control and high transparency.

Key points for avoiding pitfalls:

Confirm whether the quotation includes design, transportation, and installation service fees (usually accounting for 8-15% of the total price).

The thickness of the backboard should be at least 5mm, and the brand of the hardware should be clearly specified (the price difference between domestic and imported products can reach 3 times).

Alien designs, lighting, glass doors, etc. will incur additional charges.

Summary: Projection area has become the mainstream choice due to its simplicity and wide applicability, while unfolding area is suitable for special needs. Therefore, the pricing per meter should be cautious of implicit costs. Before signing the contract, it is necessary to confirm the configuration details and charging standards.
