Unicode does not define custom fractions like 5/16, 9/16, etc. If you want to display these after a number (e.g., 1 5/16 or 1-5/16) in a compact way, you can manually style them using superscript and subscript formatting like this:

1<span style=“font-size:66%;”><sup>5</sup>/<sub>16</sub></span>
which gives: 15/16

If you add a quotation mark (“) that does not follow a number, web browsers will typically render it as a quote mark instead of an inch symbol. To ensure it displays as an inch mark, you can use the HTML code &#8243; which renders as ″.
