Attached is a table showing the widths of the std chracter set for 12pt TNR (I used a macro to get precise measurements - see below). As you can see (and as you can show your clients) specifying something as "two characters' width" is meaningless - 'W', for instance, is 3.375 times wider than 'i', when both are at the same point size. Start changing point sizes (as you might do when changing between headings & body text) and all you achieve is an even less meaningful designation, if such were possible.
Code:
Sub GetChrWidths()
Application.ScreenUpdating = False
Dim i As Long, l As Double, r As Double, x As Long, n As Long, StrTmp As String, StrChr As String
n = 144
With ActiveDocument
With .PageSetup
.PageWidth = CentimetersToPoints(55.88)
.LeftMargin = CentimetersToPoints(0)
.RightMargin = CentimetersToPoints(0)
.TopMargin = CentimetersToPoints(0)
.BottomMargin = CentimetersToPoints(0)
End With
With .Range
.ParagraphFormat.Alignment = wdAlignParagraphLeft
With .Font
.Size = 10
.Name = "Times New Roman"
End With
For x = 32 To 255
With .Paragraphs.Last.Range
.InsertAfter vbCr
l = .Characters.Last.Information(wdHorizontalPositionRelativeToTextBoundary)
StrTmp = ""
For i = 1 To n
StrTmp = StrTmp & Chr(x)
Next
.InsertAfter StrTmp
r = .Characters.Last.Information(wdHorizontalPositionRelativeToTextBoundary)
StrChr = StrChr & Chr(x) & vbTab & Format((r - l) / n, "0.000") & vbTab
.Text = vbNullString
DoEvents
End With
Next
