Quantity surveying involves ensuring that the amount of work completed by builders corresponds to the amount that is outlined in the contract documents. This is done by comparing the two. In the event that they do not coincide, it is quite probable that either something has gone wrong or that either the quantity surveying or the mathematics of someone else has been incorrect.

Quantity surveyors are responsible for analyzing the amount of work and materials that have been completed. They also consider the amount of time necessary to complete the task as well as the number of persons involved. On-site record keeping allows a quantity surveyor to evaluate the actual results of the project in relation to the anticipated outcomes.

A difficult undertaking, the tile calculation is supported by the industry as a whole. There are a lot of tile layers and tile contractors out there who lay tiles and install tiles on a regular basis.

How to determine the number of tiles required for a floor

  1. Determine the length and width of your floor.
  2. To get the total square footage, multiply the width by the length of the area.
  3. To determine how many boxes you need, divide that total by 27, which is the number of tiles that come in a single box.
  4. Add one more tile to account for cutting and waste, and then divide the total from step 3 by 28 rather than 27 to determine the number of tiles you will require.
  5. If your room is 10 feet wide and 20 feet long, for instance, you will need six boxes of tiles in addition to one tile for cutting and trash, which brings the total number of tiles required to seven.

How to determine the number of tiles required for a wall

1. Make sure you measure both the length and width of your wall.

2. Determine how many square feet are required by multiplying the two measures together to achieve an accurate total.

3. Divide this number by 144, which is the total amount of tiles that are contained in a case (12 x 12)

4. Based on this, you will be able to determine the quantity of tile cases that are required for your project.

5. Place an order that is 5 percent higher than what you calculated because there is usually some amount of waste or breakage; additionally, it is preferable to have enough on hand than not enough.

How to determine the number of tiles required for a roof.

6. Determine the cost per tile when purchasing from a merchant either online or in-store, then divide that total by 144 to obtain the total cost of all tiles required for the project.

1. Determine the total square footage of your roof.

2. Perform a multiplication of that number by the desired length of the tiles (most commonly 12 inches)

3. Divide that total by 300 to determine the number of tiles required to cover one square foot of roofing.

4. Determine the quantity of tiles required for the complete roofing project by multiplying this amount by the total square footage of your roofing area.

5. If this is not an option, take your total square feet, divide that number by 300, and then multiply that number by 60 on a calculator (inches per foot)

How to determine the number of tiles required for a room

1. Determine the length, width, and height of your space.

2. Determine the kind of tile you want to install as well as the number of individual tiles that make up one square foot of that tile.

3. To calculate the overall area, simply multiply the length by the breadth.

4. To determine how many square feet are in your room, divide the total by 12, then multiply by 100.

5. Take this total and multiply it by the total number of squares contained in each box (found on packaging)

6. The final number is the amount required for one box; if you are purchasing six boxes at once, split this number by six; otherwise, return to step 5 and repeat the process until you have enough boxes for your project.

How to determine the number of tiles required for a kitchen

1. Determine the total area of your kitchen in square feet.

2. To determine how many tiles you need, divide the square foot into 144 to get that number.

3. Multiply that figure by two in order to account for a complete set of tiles for the wall and the backsplash.

4. If your design has any curves or patterned tile designs, add an additional ten percent to the total cost.

5. Locate a template for calculating the number of tiles required per linear foot, depending on the size and shape of your tile, so that you can precisely predict how much material you will need. You can find this template online.

6. Once you have located an exact estimate, place your order with a local retailer or an online retailer that offers free delivery alternatives.


You are a mathematical prodigy if you are able to do the calculations for tiles in your head. However, if you find that doing this without counting on your fingers or using a calculator is too difficult for you, you shouldn’t worry about it too much because there are alternative techniques to measure the area of a space that utilize its various forms and sizes.

When determining the cost of flooring depending on the square footage, you may find it helpful to utilize an online calculator such as Mathway. This type of calculator will provide you with all the necessary dimensions.
