If you are using the presentation layout library to create your issue we would always recommend setting your style up so the pages display in single page view and fill the browser window.
- Edit your style (or create a new one)
- Select 'Stretch to Width and Height' for the Single Page Stretch to Fit drop-down list:
- Set the available layouts to Single Pages:
If double-page layout is being used your issue will appear smaller in the browser.
When using single-page layouts and stretch to fit width and height the page will fill the browser making it much larger and easier to read.
