This issue has haunted us for a long time. There are two zooms now, the original cinemagraphic zoom that retains the layout while pushing the edges off the page. As if a user grabbed a magnifying glass or moved closer the reading material— this is not helped much by variations. The other, browser zoom, which scales the type and leaves the layout, has potential for using variation’s opsz, an axis in which the widths of glyphs are typically reduced as size increases, traditionally for better spacial economy on the page. In this zoom, whatever height factor the user wishes, can be scaled to, but by using optical size, the user would also get more text on the screen than scaling the type without opsz. I hope that helps. On Fri, Mar 10, 2017 at 1:42 AM, Myles C.
