This tile calculator estimates how many tiles and boxes you need for a rectangular floor or wall: enter the area's length and width, the tile size, the grout gap and a wastage percentage (10% by default), and it divides the area by the area of one tile plus its grout line, then adds the wastage and rounds up. Add the cost per tile and tiles per box to get the number of boxes and a cost estimate.
Buying too few tiles can halt your project midway, while buying too many wastes money. This guide explains the key factors in tile estimation and how to use the tile estimator.
Follow these steps:
A floor tile calculator or wall tile calculator works from four inputs: area, tile size, grout gap and wastage.
The first step is always to calculate the total surface area. For a simple rectangular area, the formula is:
Total Area = Length × Width
To determine how many tiles fit into the total area, you must first calculate the area of a single tile, including the grout lines around it.
Single Tile Area = (Tile Length + Grout Gap) × (Tile Width + Grout Gap)
Forgetting to account for the grout gap is a common mistake that can lead to buying too many tiles.
No tiling project is perfect. You will inevitably have to cut tiles to fit around edges, corners, and obstacles. Some tiles may also break during installation. To account for this, it is normal to add a wastage factor.
Our calculator applies this percentage to the number of tiles needed and rounds up, giving you extra tiles for cuts, breakage and future repairs.
Our tile cost calculator multiplies the total number of tiles (including wastage) by the cost per tile, so you can budget for the tiles before you start. It does not include adhesive, grout or labour, and it prices individual tiles rather than whole boxes. The cost is shown in ₹ in Metric mode and in $ in Imperial mode.
Our online tile calculator follows these logical steps:
This depends entirely on the size of your tiles. Use our calculator: enter 10 for length and 10 for width (feet in Imperial mode, meters in Metric mode), and then enter your tile dimensions to get the number. For example, a 10 × 10 ft room is 100 sq ft; with 12 × 12 inch tiles and a 1/8 inch (0.125) grout gap, each tile plus grout covers about 1.02 sq ft, so you need 98 tiles, or 108 with 10% wastage.
For floor tiles, a common grout line is 3mm to 5mm (about 1/8 to 3/16 inch). For wall tiles, it can be smaller, around 1.5mm to 3mm. The size often depends on the tile type and the desired look.
Always round up. Since you cannot buy a fraction of a box, you must round up to the next whole number to ensure you have enough tiles to complete your project. Our calculator does this for you automatically.
Our Tile Calculator gives a quick estimate of tiles, boxes and tile cost for a rectangular area. For L-shaped or irregular rooms, split the area into rectangles and add the results, and increase the wastage for diagonal layouts or many cuts.
