How do I zoom up to 52000% on Microsoft Visio? (I used to be able to do that)
Solution 1:
According to an old MSDN article, the max zoom is dependent on the page size and screen DPI (see below).
How Far Can I Zoom In? - Visio Insights
September 12, 2006To calculate the maximum zoom level, Visio uses this basic formula:
Max Zoom = (32767 / (Page size in inches * Screen pixels per inch)) * 100%
This formula works for me with Windows 7 and Visio 2010.
Max zoom = (32767 / (96 dpi * 11 inches)) * 100% = 3103% (close to 3098%)
Summary: To allow a higher zoom, either lower your font DPI or use a smaller page size. Font DPI is not affected by resolution or monitor dimensions.
Note: To force a DPI below 96 (100%), see this post: How to setup custom DPI below 100% on Windows 7?
