Modeling tiles in a room using Excel Conditional Formatting

Last week we learned how to answer questions like, “How many tiles in a room?” using Excel. We learned about CONVERT function and fraction number format settings in Excel.

But why stop at calculation? We can even model a room full of tiles, thanks to Excel’s grid nature.

So today, we will learn how to create a room layout like this using Excel:

Demo of Tiles in a room Excel model

If you like the demo, read on to learn.

Step 1: Set up input cells

Inputs for room & tiles model in ExcelTo model tiles in a room, we need 4 inputs. Lets call them by below names.

  • room.length
  • room.width
  • tile.length
  • tile.width

Step 2: Calculate number of tiles required

The basic formula for calculating total tiles required is this:

=ROUNDUP((room.length*room.width)/(tile.length*tile.width), 0)

But this formula yields in an unrealistic solution as we do not want to have fractional tiles everywhere. So, a better way to calculate this is,

=ROUNDUP(room.length / tile.length,0) * ROUNDUP(room.width / tile.width,0)

Although this formula is technically correct, you may save a few tiles if you rotate the them.

That is,

ROUNDUP(room.length / tile.width,0) * ROUNDUP(room.width / tile.length,0) can be smaller than ROUNDUP(room.length / tile.length,0) * ROUNDUP(room.width / tile.width,0) in some cases, as shown in above demo.

So we need a way to flip tile dimensions if that saves us a few bucks. That is done by,

Step 3: Flipping tile dimensions with a switch

Insert a check box and link to a blank cell, say F6.

[Related: How to use a check box in Excel]

Now, using F6 value (either TRUE or FALSE), flip the values of tile.length & tile.width using IF() formula.

Step 4: Create a 100×100 grid

Although you can model the floor plan of entire Buckingham palace in Excel, lets restrict ourselves to rooms of size 100×100.

Select 101 columns and resize them small enough so you can see all of them in a single screen, like 10 pixels wide.

Select 101 rows and adjust their height so that you can see as many of them as possible in a single screen (10 pixels tall should do).

Type running numbers in first column & row. The final grid looks this this:

Floor tiles model in Excel by setting up 100x100 cell grid

Step 5: Modeling the room layout using conditional formatting

So we have a big 100×100 grid where we need to draw

  • Outer boundary for the room as per room.length & room.width
  • Inner tile boundaries as per tile.length & tile.width

Set up conditional formatting rules for room boundary

There are 4 rules required.

  1. Draw vertical left border if the topmost row = 1
  2. Draw vertical right border if the topmost row = room.length
  3. Draw horizontal top border if the left-most column = 1
  4. Draw horizontal bottom border if the left-most column = room.width

Below, see one of the rules.

Conditional formatting rule for room boundary explained

You can find other conditional formatting rules in the downloadable workbook.

Step 6: Modeling Tiles using conditional formatting

While we need 4 rules for the room boundary, we just need 2 rules for tile boundaries.

  1. Draw vertical right border if the topmost row value is divisible by tile.length
  2. Draw horizontal bottom border if the left-most column value is divisible by tile.width

We do not need rules for vertical left border or horizontal top border because they will be drawn by previous tile.

See one of the rules below:

That’s all. Our room model is ready. Go ahead and see how it looks when tile it.

Do you apply Conditional Formatting in such creative ways?

I personally think conditional formatting is as good as honey, mangoes or dark chocolate. I love to use a dollop of it in all my Excel recipes.

What about you? Do you use conditional formatting for anything out-of-box 😉 like this? Please share your tips using comments.

    Would be considerably easier just to have a table with the variance shown.

  2. Jomili says:

    On Step 3, how do you "Add budget and actual values to the chart again"?

    • Chandoo says:

      There are a few ways to do it.

      Easy:
      1) Copy just the numbers from both columns (Select, CTRL+C)
      2) Select the chart and hit CTRL+V to paste. This adds them to chart.

      Traditional:
      1) Right click on chart and go to "select data..."
      2) From the dialog, click on "Add" button and add one series at a time.

      • Neeraj Agarwal says:

        One more way to accomplish it is just select the columns into chart. Press Ctrl+C and then press Ctrl+V

  3. TheQ47 says:

    Unfortunately, this doesn't seem to work for me in Excel 2010. The "Var 1" and "Var 2" columns cannot combine two fonts to display the symbol and the figure side-by-side.
    Secondly, there is no option to Click on “Value from cells” option when formatting the label options. The only options provided are Series Name, Category Name or Value.

    • Chandoo says:

      @TheQ47... the emoji font also has normal English letters, so if you use that font, then you should be ok. I am assuming your computer doesn't have that font or hasn't been upgraded for emoji support.
      Reg. Excel 2010, you can manually link each label to a cell value. Just select one label at a time (click on labels, wait a second, click on an individual label) and press = and link it to the label var 1 or var 2.

    I am using excel 2010, please explain how to apply Step 12

    Hi Chandoo,

    I just found your website, and really love it. It helps me a lot to be an Excel expert 😉

    Currently I am facing with a problem at step 11:
    Var1 Var2
    D30%
    A5%
    B0%
    B4%
    B7%
    C10%
    C13%
    D27%
    I42%

    Though at mapping table, I used windings, here formula uses calibra. How I can change it? I am able to change only the whole cell. In this case numbers will be Windings too.

    Thanks for your help!

    • Chandoo says:

      Hi Mariann... Welcome to Chandoo.org and thanks for your comment.

      If you wanted to use symbols from wingdings and combine them with % numbers, then you need to setup two labels. One with symbol, in wingdings font and another with value in normal font. Just add the same series again to the chart, make it invisible, add labels. You may need to adjust the alignment / position of label so everything is visible.

  6. […] firs article explains how you can enhance your charts with symbols. You can simply insert any supported symbol into your data and charts. To some extend you can […]

    You're a good person, thank you to share your knowledge with us, I will try to do in my work

  8. Ali says:

    Great visualization of variance. My question is that is this possible in powerbi?

    How would you go about it?

  9. NARUTO says:

    HELLO, WHY CANT I FIND VALUES FOR LABELS IN EXCEL 2013

  10. Amol says:

    Dear chanddo sir,

    What to do if we have dynamic range for Chart. How this will work. can you able to make the same thing works on dynamic range.

  11. Ricardo says:

    Sir Chandoo,

    Good Day!
    First, I'd like to say that I am very grateful for your work and for sharing all these things with us.

    I tried to do this chart but it seems that the symbols don't work with text (abs(var%),"0%") unless we keep the Windings font style.
    The problem is, it converts the text into symbol as well and you wont see the 0% anymore. I'm using Windows 7.

    Sir This is awesome chart, and very easy to made because of your way to explain is very simple , everyone can do. Thank you

    one problem i am facing, I hv made this chart , but when i am inserting data table to chart it is showing two times , how can i resolve this

  14. renuka says:

    in this chart when i am adding new month data for example first i made this chart jan to mar but when i add data for the apr month graphs updated automatically but labels are missing for that new month

    • Chandoo says:

      Hi Renuka,

      Please make sure the formulas for labels are also calculated for extra months. Just drag down the series and set label range to appropriate address.

  15. Justine says:

    So I am playing with the Actual chart here - but amounts are bigger than your - you have 600 as Budget - my budget is 104,000 - is there a way to shorten that I am unaware of

    thank you - I LOVE YOUR SITE

  16. Arvind says:

    Thanks for the tips and tricks on Excel. In the Planned versus Actual chart examples, you use multiple values (ex. multiple Categories in above). How can this be done when we have only 1 set of values? For example if I have only this:
    Planned Actual
    SOW Budget 417480 367551

    How can I create a single bar chart like the one above?

  17. JEREMIAH KOOL says:

    Thank you Chandoo.
    This one is just perfect for my Quarterly Review presentation on Operational Budget against Actual Performance for the Hospital I'm currently working with.

  18. Shawn says:

    Is there a way to make the table of data into a pivot table to be able to add a slicer for the graph due to many different categories and months?

  19. Mihail says:

    Hi, I tried to modify you template with something appropriate for me, and I found a problem. this template was modified by me started with excel 2010, then 2016 and finally 2019. Same thing - somehow appear an error - or didn't show the emoticons for positive percentage or doubled the emoticons for some rows. I suspect to be from excel. if is need it I can sand you my xlsx for study. Please help if you can.

  20. Saidatta Pati says:

    Hi Chandoo,
    Could you please check the Var Formula in Step1. You have mentioned budget-actual and when i did this i got different values but when reversed like actual-budget i got the actual value what you have demonstrated in step1.
    Please share your view.

  21. Dan says:

    This is a great chart (budget vs. actual). However, in trying recreate it, I cannot color in the UP Down bars individually, and they all become formatted with the same color. I'm using Office 365. Look forward to the feedback.

    Thanks.
    Dan

  22. sathik says:

    pls explain in detail step 7

  23. Arun says:

    While in the Excel sheet you have used following formula for Var
    Var = Actual - Budget
    But
    in the note, you have written
    Var = Budget - Actual
