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>"
Hi wcarter
1️⃣ Use a Text Box Instead of a Card
Power BI Text Boxes allow much larger font sizes, beyond 60pt.
Steps:
1. Insert → Text box
2. Type your value (can be dynamic using a measure via Value → fx)
3. Set the font size above 60 (up to ~300)
4. Format background and alignment to mimic a card
Pros: fully scalable font, customizable design
Cons: Slightly less dynamic than native card (requires measure formatting)

2️⃣ Use a Multi-Row Card Visual
Multi-row card can sometimes bypass the 60pt limit for individual fields.
Steps:
1. Insert → Multi-row card
2. Add your measure
3. Format each field’s data label → may allow slightly larger sizes than single card
Note: Still limited, but sometimes larger than 60pt

3️⃣ Use a Custom Visual from AppSource
Custom card visuals may allow larger font sizes or free-form scaling:
Examples:
Card with States
Card Browser
Infographic Designer
Steps:
1. Visualizations → Get more visuals → AppSource
2. Search “Card” or “KPI”
3. Import visual → Add to dashboard → adjust font freely

4️⃣ Combine Shapes + Text Boxes
If you want a “card look” with very large numbers:
Insert rectangle / shape
Overlay Text Box with large font
Bind the Text Box to a measure
Adjust colors / borders to match card style
