Advanced AutoFit Techniques

AutoFit with Maximum Width

Limit column width to prevent too-wide columns:

VBA Code:

Sub AutoFitWithMax()
    Dim col As Range
    For Each col In Selection.Columns
        col.AutoFit
        If col.ColumnWidth > 50 Then
            col.ColumnWidth = 50
        End If
    Next col
End Sub

AutoFit Based on Header

AutoFit to header width only:

Sub AutoFitHeaders()
    Dim col As Range
    For Each col In Selection.Columns
        col.ColumnWidth = Len(Cells(1, col.Column).Value) + 2
    Next col
End Sub

AutoFit with Wrap Text

AutoFit height when text wraps:

  1. Select cells
  2. Home > Wrap Text
  3. Home > Format > AutoFit Row Height

Tips for Best Results

1. AutoFit After Data Entry

Best practice:

  • Enter all data first
  • Then AutoFit columns
  • Prevents constant readjustment

2. AutoFit Before Printing

Before printing:

  • AutoFit all columns
  • Check print preview
  • Adjust if needed

3. Use Consistent Widths

For similar data:

  • Set same width for similar columns
  • Looks more professional
  • Easier to read

4. Consider Screen Size

For mobile viewing:

  • Limit column widths
  • Use wrap text
  • Consider portrait orientation

5. AutoFit Headers Separately

If headers are longer than data:

  • AutoFit header row first
  • Then auto-fit data columns
  • Or set header width manually

Troubleshooting AutoFit Issues

Problem: Columns Don't Adjust

Solutions:

  • Check if cells are merged (AutoFit doesn't work on merged cells)
  • Unmerge cells first
  • Or adjust manually

Problem: Columns Too Wide

Solutions:

  • Set maximum width
  • Use wrap text instead
  • Manually set narrower width

Problem: AutoFit Too Slow on Large Sheets

Solutions:

  • AutoFit specific columns only
  • Use VBA with screen updating off
  • Or set fixed widths for large datasets

Problem: Print Still Doesn't Fit

Solutions:

  • Use Page Layout > Scale to Fit
  • Set width to 1 page
  • Or use landscape orientation
