Font Size

Hi wcarter 

You're right that max font size limit in Power BI is 60. A workaround is to use a DAX generated SVG image returning the desired value. The first card in the image below uses SVG while the second one uses the 60px limit. This is fine for a few measures but quite tricky to setup. DAX below was generated with the help of AI

SVG_Responsive_Text =
VAR _label = "Total Sales:"
VAR _value = FORMAT( [Total Transactions], "#,0" )

-- Large viewBox for better scaling
VAR _vbW = 2000
VAR _vbH = 1000

-- Padding inside viewBox
VAR _padX = _vbW * 0.05
VAR _padY = _vbH * 0.1

-- Font size relative to viewBox height
VAR _fontSize = _vbH * 0.35

-- Text position
VAR _x = _padX
VAR _y = _vbH / 2   -- vertically centered

RETURN
"data:image/svg+xml;utf8," &
"<svg xmlns='http://www.w3.org/2000/svg' "
& "width='100%' height='100%' "
& "viewBox='0 0 " & _vbW & " " & _vbH & "'>"
    & "<rect width='100%' height='100%' fill='white'/>"
    & "<text x='" & _x & "' y='" & _y & "' "
        & "font-family='Segoe UI' "
        & "font-size='" & _fontSize & "' "
        & "dominant-baseline='middle' "
        & "text-anchor='start'>"
        & _label & " "
        & "<tspan font-weight='700'>" & _value & "</tspan>"
    & "</text>"
& "</svg>"
