Sand Calculator — Concrete, Plaster & Filling Quantities
Sand is bought by the foot (cft) or by the trolley/ton on Pakistani sites, and rates swing sharply between Chenab and Ravi quality. This sand calculator converts your concrete, plaster or filling volumes into cft and tons so you can compare supplier quotes fairly.
Quick Answer
One ton of sand is roughly 20 cft, and a standard 5 marla house uses 1,500–2,000 cft of sand across slab, plaster and filling. Enter your project dimensions below to get sand in cft and tons with estimated cost.

How to Use the Sand Calculator
- 1Pick the use case — concrete mix, plaster, or bedding/filling.
- 2Enter the area or volume you need to cover, with thickness for slabs and plaster.
- 3Read the result in cft and tons, then price it at your local rate per cft.
- 4Order per trolley: a standard trolley carries roughly 150–250 cft depending on the truck.
Frequently Asked Questions
How much sand is required for 100 sq ft of plaster?
For 12 mm (½ inch) plaster at a 1:4 mix, 100 sq ft needs about 4–5 cft of sand and roughly one 50-kg cement bag. External 20 mm plaster needs roughly double: 8–9 cft sand and about 2 bags.
How many cft are in one ton of sand?
Loose river sand weighs about 90–100 kg per cft, so one ton is roughly 20 cft. Chenab sand can be slightly lighter; always confirm with your supplier's weighing, and buy by weighed ton where possible.
Which sand is best for house construction in Pakistan?
Chenab sand (washed, coarse) is preferred for concrete and plaster; Ravi sand is cheaper but needs more cement. For slabs, use washed sand with low silt — do the jar test: silt should settle under 8% of the water column.
