Calculate how many bags of mortar or thinset you need for tile and brick projects. Adjusts for trowel size, joint thickness, and tile surface type.

Total tile surface area
Coverage: ~2.5 m²/bag
Extra material for waste and spillage
25kg bag price for cost estimate
4 bags calculated, rounded up
Based on selected settings
Measure your total tile area in square meters. Include all walls and floors that will be tiled.
Larger notches deposit more thinset, reducing coverage per bag but ensuring better tile adhesion.
Textured tile backs use approximately 15% more thinset to fill the ridges and ensure proper bonding.
Results include your waste factor to ensure you have enough material for the job.
Measure your brick wall area in square meters. This is the visible face area of the wall.
Standard is 10mm. Thicker joints (12mm) use more mortar but provide a rustic look.
10% is typical for most projects. Increase for complex walls or irregular brick sizes.
See both bags needed and approximate number of bricks this will cover.
Coverage rates are based on 25kg bags of standard-grade products. Premium or modified thinsets may have different coverage. Always check manufacturer specifications for your specific product. The waste factor accounts for normal spillage, dropped material, and application variations.
Concrete Slab Calculator
Estimate concrete volume in cubic meters and bag counts for slabs, footings, and pads based on length, width, and thickness.
Concrete Bags Calculator
Convert a concrete volume into the number of pre-mix bags you need, with options for common bag sizes and mix strengths.
Rebar Calculator
Calculate reinforcing steel bar count, total length, and weight for concrete slabs and footings based on spacing and bar size.
Block Wall Calculator
Estimate CMU blocks and mortar bags for masonry walls based on wall dimensions, block size, and joint thickness.
