Above the fold

What is visible before anybody scrolls, named after the top half of a folded newspaper on a stand.

the useful part	everything below the first screen is a scroll a reader has to decide to make, so the first screen has to earn it
the harmful part	treating it as a box to cram the whole page into
measured on our own site, on a phone	at 390x844 the home page's first screen holds 8 words across 7 blocks and 8 links, and the page is 5.9 screens long. THE BAR TAKES 117 OF THE 757 USABLE PIXELS, which is 15.5 per cent of the first screen spent before any content at all	measured on the built site in a headless Chromium at two viewports, counting every element whose box falls inside the first screen
and on a desktop the same bar costs 8.7 per cent	at 1440x900 the bar is 71px of 813 and the first screen holds 16 words	the header costs nearly twice as much of a phone screen as of a desktop one, which is the opposite of where the room is. A figure about the fold is really a figure about the chrome
the wiki board, for comparison	at 390x844 its first screen holds 46 words, 28 links and 17 pictures, over 6 screens	measured on the built site in a headless Chromium at two viewports, counting every element whose box falls inside the first screen
