How to Use the SGFloorHub Flooring Area Calculator

Use the Flooring Area & Wastage Calculator when you need a clear room-by-room quantity record for a flooring enquiry. It separates the area you measure from the material you may need to order. The short visual guide below shows the workflow; this article explains the choices behind each step.

Use the Flooring Area & Wastage Calculator when you need a clear room-by-room quantity record for a flooring enquiry. It separates the area you measure from the material you may need to order. The short visual guide below shows the workflow; this article explains the choices behind each step.

1. Choose units and enter the rooms

Open the calculator and select metres or feet. For a rectangular room, enter length and width in the same unit. Add another room when the project covers more than one space, and rename each entry so the summary stays useful. For an irregular space, choose the measured-area option and use the quantity from an appropriate measured plan. Avoid forcing an L-shaped room into one oversized rectangle. The sample-room buttons add illustrative entries; they are not verified dimensions for your HDB flat or condominium.

Live calculator example: 20 m² living room + 12 m² bedroom = 32 m² measured; 15 hypothetical 2.5 m² packs give a 37.5 m² order.

2. Make inclusions and exclusions visible

Keep the included-room checkbox selected only for spaces in the intended scope. If the project covers bedrooms but leaves the kitchen or balcony unchanged, record that distinction. Measure doorways, recesses and transitions consistently with the provider’s method. The worked example uses a 20 m² living room and a 12 m² bedroom, giving 32 m². Check the room names and dimensions before calculating, because accurate arithmetic cannot correct an incorrect measurement.

3. Enter the ordering assumptions

Ask the supplier to confirm the allowance for the actual product, room geometry and laying pattern. The starting 10% is editable, not a universal recommendation. If the product is sold in packs, enter the coverage printed on the actual product information. The screenshot shows a hypothetical 2.5 m² pack. Leaving pack coverage blank means the tool cannot round the order to whole packs. Broadloom roll widths, seams and pattern matching need a separate cutting plan.

Enter the supplier-confirmed allowance and actual pack coverage. The 10% allowance and 2.5 m² pack shown are demonstration inputs.

4. Read the result and keep the record

Click Calculate area. For the example, 32 × 1.10 gives a target of 35.2 m². Dividing by 2.5 and rounding up gives 15 packs, or 37.5 m². The extra from pack rounding is 2.3 m² beyond the target. Use this area in Budget Planner carries the measured and order quantities within the same browser tab when browser storage is available. Alternatively, copy the summary or print/save it as a PDF. Confirm the final measured layout and product-specific order with the provider before buying material.

Read the example quantity record

Input or result Example How to interpret it
Living room 5 × 4 m = 20 m² Illustrative rectangular room
Bedroom 4 × 3 m = 12 m² Illustrative rectangular room
Measured area 32 m² Included room areas added together
Allowance input 10% = 3.2 m² Demonstration only; confirm for the product and layout
Target area 35.2 m² Measured area plus the allowance
Pack coverage 2.5 m² per pack Hypothetical coverage; use the actual product value
Whole packs and order 15 packs = 37.5 m² Target divided by coverage, rounded up

Pack rounding adds 2.3 m² beyond the 35.2 m² target. It does not establish batch availability, return terms or a broadloom cutting plan.

Practical questions

Can I use the room presets as my flat’s dimensions?

No. They are illustrative entries. Rename and replace them with the dimensions of your own rooms.

How do I enter an L-shaped room?

Use non-overlapping rectangles as separate entries, or choose measured area and enter a properly measured net quantity. Avoid counting the shared part twice.

Can I deduct a wardrobe footprint?

Confirm whether flooring is intended under that unit and follow the selected system’s installation instructions. Do not assume every fixed or modular unit should be included or excluded.
