How to auto fit row height of merged cells in Excel?

In Excel, we can quickly adjust the row height to the fit the cell contents by using the AutoFit Row Height feature, but this function will completely ignores merged cells. That is to say, you can’t apply the AutoFit Row Height feature to resize the row height of merged cells, you need to manually adjust the row height for merged cells one by one. In this article, I can introduce some quick methods to solve this problem.

Auto fit row height of merged cells with VBA code


arrow blue right bubble Auto fit row height of merged cells with VBA code

Supposing I have a worksheet with some merged cells as following screenshot shown, and now I need to resize the cell row height to display the whole contents, the below VBA code may help you to auto fit the row height of multiple merged cells, please do as follows:

doc-autofit-merged-cells-1

1. Hold down the ALT + F11 keys, and it opens the Microsoft Visual Basic for Applications window.

2. Click Insert > Module, and paste the following code in the Module Window.

VBA code: Auto fit row height of multiple merged cells
Option Explicit
Public Sub AutoFitAll()
  Call AutoFitMergedCells(Range("a1:b2"))
   Call AutoFitMergedCells(Range("c4:d6"))
    Call AutoFitMergedCells(Range("e1:e3"))
End Sub
Public Sub AutoFitMergedCells(oRange As Range)
  Dim tHeight As Integer
  Dim iPtr As Integer
  Dim oldWidth As Single
  Dim oldZZWidth As Single
  Dim newWidth As Single
  Dim newHeight As Single
  With Sheets("Sheet4")
    oldWidth = 0
    For iPtr = 1 To oRange.Columns.Count
      oldWidth = oldWidth + .Cells(1, oRange.Column + iPtr - 1).ColumnWidth
    Next iPtr
    oldWidth = .Cells(1, oRange.Column).ColumnWidth + .Cells(1, oRange.Column + 1).ColumnWidth
    oRange.MergeCells = False
    newWidth = Len(.Cells(oRange.Row, oRange.Column).Value)
    oldZZWidth = .Range("ZZ1").ColumnWidth
    .Range("ZZ1") = Left(.Cells(oRange.Row, oRange.Column).Value, newWidth)
    .Range("ZZ1").WrapText = True
    .Columns("ZZ").ColumnWidth = oldWidth
    .Rows("1").EntireRow.AutoFit
    newHeight = .Rows("1").RowHeight / oRange.Rows.Count
    .Rows(CStr(oRange.Row) & ":" & CStr(oRange.Row + oRange.Rows.Count - 1)).RowHeight = newHeight
    oRange.MergeCells = True
    oRange.WrapText = True
    .Range("ZZ1").ClearContents
    .Range("ZZ1").ColumnWidth = oldZZWidth
  End With
End Sub

Notes:

(1.) In the above code, you can add new ranges just copy Call AutoFitMergedCells(Range("a1:b2")) script many times as you want, and change the merged cell ranges to your needed.

(2.) And you should change the current worksheet name Sheet4 to your used sheet name.

3. Then press F5 key to run this code, and now, you can see all the merged cells have been auto fitted to their cell contents, see screenshot:

Perfect, good job! A just not ajust with merge cells in the same colum, there is an error with this code on the script:

For exemple if i want ajust this range ("a32:i32"):

Call AutoFitMergedCells(Range("a32:i32"))

Apear an error in this line of the script:

.Rows(CStr(oRange.Row) & ":" & CStr(oRange.Row + oRange.Rows.Count - 1)).RowHeight = newHeight

Could you help me?

Hi All,

I modify the codes, which will search the merged cells and apply the autofit. hope this will help the future if any one interested.


Sub FindMergedCells()

' Declare sheet you want to look for merged cells on - in the example it's sheet 1
Dim sheet As Worksheet
Set sheet = ActiveWorkbook.Sheets(1)
Dim rng As Range
Dim rngStart As Range
Dim rngEnd As Range
Dim tHeight As Integer
Dim iPtr As Integer
Dim oldWidth As Double
Dim oldZZWidth As Double
Dim newWidth As Double
Dim newHeight As Double
Dim oRange As Range


' Add sheet for output
Dim output As Worksheet
Set output = Sheets.Add(after:=Sheets(1))

' Initialize row counter for output
orow = 0

' Header on output sheet


' Check all the cells in the worksheet's used range
For Each cell In sheet.UsedRange

' If they're merged -

If cell.MergeCells Then
orow = orow + 1
Set cell = cell.MergeArea
Set rngStart = cell.Cells(1, 1)
Set rngEnd = cell.Cells(cell.Rows.Count, cell.Columns.Count)

'MsgBox "First Cell " & rngStart.Address & vbNewLine & "Last Cell " & rngEnd.Address
'output.Cells(orow, 1) = "" & Replace(rngStart.Address, "$", "") & ":" & Replace(rngEnd.Address, "$", "")
Set oRange = Range("" & Replace(rngStart.Address, "$", "") & ":" & Replace(rngEnd.Address, "$", ""))

With sheet
oldWidth = 0
For iPtr = 1 To oRange.Columns.Count
oldWidth = oldWidth + .Cells(1, oRange.Column + iPtr - 1).ColumnWidth
Next iPtr
'oldWidth = .Cells(1, oRange.Column).ColumnWidth + .Cells(1, oRange.Column + 1).ColumnWidth
oRange.MergeCells = False
newWidth = Len(.Cells(oRange.Row, oRange.Column).Value)
oldZZWidth = .Range("ZZ1").ColumnWidth
.Range("ZZ1") = Left(.Cells(oRange.Row, oRange.Column).Value, newWidth)
.Range("ZZ1").WrapText = True
.Columns("ZZ").ColumnWidth = oldWidth
.Rows("1").EntireRow.AutoFit
newHeight = .Rows("1").RowHeight / oRange.Rows.Count
.Rows(CStr(oRange.Row) & ":" & CStr(oRange.Row + oRange.Rows.Count - 1)).RowHeight = newHeight
oRange.MergeCells = True
oRange.WrapText = True
.Range("ZZ1").ClearContents
.Range("ZZ1").ColumnWidth = oldZZWidth
End With
Else

'MsgBox "Not merged area"

End If
Next cell

End Sub

I have tried this as I am not at all proficient with VBA. At the "Set Sheet = Activeworkbook I always get this Compile Error - Invalid outside procedure. What am I doing wrong?

Works perfectly on a single sheet. I need to fit multiple worksheet cells in one file. can you help me?

It works perfectly. However, I need to adjust the width of multiple worksheets. it's possible?
This comment was minimized by the moderator on the site
There is a limit on the size - if the total height required is greater than 409.5, it will only do what would fit in 409.5 and spread it amongst the height of the merged cells and you would not see the remainder.  I was hoping this would solve for text lengths greater than the max row height (409.5).  I think you may need to iterate through and split the text to what can fit in to the first max height of 409.5 then put the rest in another cell (ZZ2) and so on until it fits, then count the rows in each cell then get the total required height.

Dang it, copy/paste bit me. Also, with explicit sheet references the With isn't needed:

Public Sub AutoFitMergedCells(oRange As Range, ByVal dblWidth As Double)



oRange.MergeCells = False

Sheet1.Range("A1") = oRange.Cells(1, 1).Value

Sheet1.Range("A1").WrapText = True

Sheet1.Columns(1).ColumnWidth = dblWidth

Sheet1.Rows(1).EntireRow.AutoFit

oRange.Parent.Rows(oRange.Row).Resize(oRange.Rows.Count).RowHeight _

= Sheet1.Rows(1).RowHeight / oRange.Rows.Count

oRange.MergeCells = True

oRange.WrapText = True



End Sub

Thank you, that helped me with a sheet I've not been happy with for years.

I did change things around a bit, my merged cells are all in one column so I calculated that outside the loop and passed it. I also inserted a Sheet1 that is hidden, and manipulated the columns/rows there so as to not affect the sheet I'm working on. The references should probably be more explicit:

Public Sub AutoFitMergedCells(oRange As Range, ByVal dblWidth As Double)



Dim dblHeight As Double



With oRange.Parent

oRange.MergeCells = False

Sheet1.Range("A1") = oRange.Cells(1, 1).Value

Sheet1.Range("A1").WrapText = True

Sheet1.Columns(1).ColumnWidth = dblWidth

Sheet1.Rows(1).EntireRow.AutoFit

dblHeight = Sheet1.Rows(1).RowHeight / oRange.Rows.Count

oRange.Parent.Rows(oRange.Row).Resize(oRange.Rows.Count).RowHeight = newHeight

oRange.MergeCells = True

oRange.WrapText = True

Sheet1.Range("A1").ClearContents

End With



End Sub

I believe the reason that the row heights do not calculate properly is related to these lines of code
For iPtr = 1 To oRange.Columns.Count
oldWidth = oldWidth + .Cells(1, oRange.Column + iPtr - 1).ColumnWidth
Next iPtr
oldWidth = .Cells(1, oRange.Column).ColumnWidth + .Cells(1, oRange.Column + 1).ColumnWidth

The variable OldWidth gets set to the sum of the column widths in the range, but for some reason it gets reset to only the width of the first two columns. The first 3 lines of code are therefore made redundant by the 4th line. When I removed the line it was much better, but the other issue I found was that you have to make sure that the font and font size of the temporary cell (ZZ1 in the example code) must match the font and size of the merged cells; otherwise, text will not wrap in the same way as the merged cells wrap and may not be the correct height.

This is pretty helpful, thanks!

I am trying to understand the necessity of Line 19. You are assigning a value again to OldWidth. Can you please explain?
