Estimate carpeting and tile.
Introduction

If you are thinking about replacing the
 flooring in a room of your house, you may
 find the tips in this tutorial useful.
There are only two steps required:
      1.) Determine the area of the room.

      2.) Convert the area measurement to square
      feet or square yards as necessary.
Introduction

All you will need to do these things are a
 tape measure and a basic calculator.
Introduction

Assuming that your room is simply
 rectangular in shape, measure the length
 and the width in inches.
         Length


                       Note: This diagram represents a
      Utility Room     “bird’s eye” view of the room.
Introduction

Note the measurements for this
 example...
                         Length = 144”
        144 inches       Width = 90”



      Utility Room
Introduction

To determine the area of the room,
 multiply the length by the width.
                         Length = 144”
        144 inches       Width = 90”

                         Area = Length x Width

      Utility Room
Introduction

To determine the area of the room,
 multiply the length by the width.
                         Length = 144”
        144 inches       Width = 90”
                                144” x 90”
                         Area = 12,960 sq. in.

      Utility Room
Introduction

Next, convert your area measurement.
What you convert to depends upon what
 kind of flooring you are buying.
                              Click on the button next to
         144 inches           the type of flooring that you
                              are buying:
                              Vinyl tiles
      Utility Room            Carpeting/ or sheet vinyl
      Area = 12,960 sq. in.
                              Ceramic tile
Vinyl Tiles

You want to know how many vinyl tiles it
 will take to cover the floor...


                       Room = 12,960 sq. in.




1 tile = 1 sq. ft.
                              etc...
Vinyl Tiles

Since tiles are sold by the square foot,
 you will need to convert your room area
 from square inches to square feet.
Vinyl Tiles

To do this, you need to know how many
 square inches are equal to 1 square foot.
                     1 ft         12 in
            1 ft




                   1 sq ft

       Now picture represents 1using inch
       This re-label the square square foot.
       dimensions instead of feet.
Vinyl Tiles

To do this, you need to know how many
 square inches are equal to 1 square foot.
                      1 ft          12 in
             1 ft




                    1 sq ft   Area = 12 in x 12 in
       Complete the multiplication to find the area in
       square inches.

To do this, you need to know how many
 square inches are equal to 1 square foot.
                     1 ft        12 in
            1 ft




                   1 sq ft     144 sq in
       Now you know that 1 sq ft = 144 sq in
Vinyl Tiles

To finish, simply divide your room area by
 144:

      Room Area (sq in) ÷ 144 = Room Area (sq ft)

            12,960 sq in ÷ 144 = 90 sq ft

       The answer tells you that you need at least 90
       vinyl tiles to cover the floor. Due to trimming
       and cutting mistakes you will certainly need to
       buy more than 90 tiles.

Sheet vinyl and carpeting

You will need to change the room area
 from square inches to square yards
 because sheet vinyl and carpeting are sold
 by the square yard.
                              This must be
                              converted to square
      Utility Room            yards.
      Area = 12,960 sq. in.
Sheet vinyl and carpeting

How many square inches are equal to one
 square yard?
                   1 yd         36 in
           1 yd




                  1 sq yd

      Now re-label the square square yard.
      This picture represents 1 using inch
      dimensions instead of yards.
Sheet vinyl and carpeting

How many square inches are equal to one
 square yard?
                   1 yd           36 in
           1 yd




                  1 sq yd   Area = 36 in x 36 in

       Complete the multiplication to find the area in
       square inches.
Sheet vinyl and carpeting

How many square inches are equal to one
 square yard?
                   1 yd        36 in
           1 yd




                  1 sq yd    1296 sq in
      Now you know that 1 sq yd = 1296 sq in
Sheet vinyl and carpeting

To finish, simply divide your room area by
 1296:

      Room Area (sq in) ÷ 1296 = Room Area (sq yds)

             12,960 sq in ÷ 1296 = 10 sq yds
       The answer tells you that you need at least 10
       sq yds of carpeting to cover the floor. Due to
       the way carpeting and sheet vinyl is sold you
       will probably end up buying somewhat more.

Ceramic Tile

Ceramic tile is sold in a variety sizes.
To determine the number you have to
 buy, compute the area of one tile in
 square inches.

Area=12 in x in in   Area=8 in x in in Area=6 in x in in

Ceramic Tile

Now, divide room area by the area of one
 tile.     Number of tiles = room area ÷ tile area

 Let’s do the        Number of tiles = 12,960 sq in ÷ 144 sq in
 12” tile first...
      12 in          Number of tiles = 90 tiles (12” size)
                        8 in
                                         6 in            4 in
                     8 in




                                      6 in




                                                      4 in
Area=144 sq in       Area=64 sq in   Area=36 sq in   Area=16 sq in
Ceramic Tile

Now, divide room area by the area of one
 tile.     Number of tiles = room area ÷ tile area
                 Number of tiles = 12,960 sq in ÷ 64 sq in

     12 in       Number of tiles = 203 tiles (8” size)
                    8 in
                                     6 in            4 in
                 8 in




                                  6 in




                                                  4 in
Area=144 sq in   Area=64 sq in   Area=36 sq in   Area=16 sq in
                 …now the 8”
                 tile...
Ceramic Tile

Now, divide room area by the area of one
 tile.     Number of tiles = room area ÷ tile area
                 Number of tiles = 12,960 sq in ÷ 36 sq in

     12 in       Number of tiles = 360 tiles (6” size)
                    8 in
                                     6 in            4 in
                 8 in




                                  6 in




                                                  4 in
Area=144 sq in   Area=64 sq in   Area=36 sq in   Area=16 sq in
                                 …next the 6”
                                 tile...
Ceramic Tile

Now, divide room area by the area of one
 tile.     Number of tiles = room area ÷ tile area
                 Number of tiles = 12,960 sq in ÷ 16 sq in

     12 in       Number of tiles = 810 tiles (4” size)
                    8 in
                                     6 in            4 in
                 8 in




                                  6 in

                                                 …and lastly the

Allowances

Common sense tells you that it is not a
 good idea to buy the exact amount of
 vinyl or ceramic tile that you calculate for
 a room.
Some manufacturers have suggested
 “breakage allowances” that help you
 estimate how much more tile to buy.
   Allowances

    These allowances are often expressed as
     a percent.
    For example, a tile manufacturer might
     tell you to buy 10% extra.
Extra tiles required = Calculated Number of Tiles Needed x Manufacturer’s Allowance

                  Suppose you calculate that you need
                  370 tiles for your floor. If the
                  allowance is 10%, how many extra
                  should you buy?
   Allowances

    These allowances are often expressed as
     a percent.
    For example, a tile manufacturer might
     tell you to buy 10% extra.
        Change this to .10 when you
        type it into Calculated Number
Extra tiles required =your calculator. of Tiles Needed x Manufacturer’s Allowance



                  Extra tiles required = 370 x 10%
   Allowances

    These allowances are often expressed as
     a percent.
    For example, a tile manufacturer might
     tell you to buy 10% extra.
Extra tiles required = Calculated Number of Tiles Needed x Manufacturer’s Allowance


                                         37 x .10
                  Extra tiles required = 370tiles
Allowances

If the allowance had been a different
 amount, you would still follow the same
 procedure.

15% Allowance:   Extra Needed = 370 tiles x 15%
                 Extra Needed = 370 tiles x .15
                 Extra Needed = 56
