Field notes
Playbooks, teardowns and the occasional argument — everything we have learned helping creators grow across every major platform.
Gmail on a desktop gives a subject line about 340 pixels — the tightest surface in email. A phone gives more. The count that matters is a width, not a character total.
Emoji in captions cost more characters than you think, are announced aloud by screen readers, and render differently on every device. Here is how to use them well.
Title case and sentence case are conventions, not rules, and the styles disagree with each other. Here is what each does and which to pick.
Words per minute speaking varies from 110 to 160 depending on format. Here is how to convert a script to a runtime before you record it.
Readability scores measure sentence and word length, not clarity. Here is what a readability score actually tells you and how to use one sensibly.
Facebook ad text is truncated long before the field limit. Here are the recommended lengths for primary text, headline and description, and where each cuts.
LinkedIn cuts a post after two or three lines. Here is where the fold actually falls, why it differs on mobile, and how to write the visible part.
The Threads character limit is 500. Longer text chains into a second post rather than being rejected, which changes how you should write for it.
TikTok caption length matters twice: the fold decides what is read, and the caption itself covers part of your video. Here is how to work with both.
The Twitter character limit is 280 for most accounts, but URLs, emoji and non-Latin scripts are not counted one-for-one. Here is how the weighting works.
Instagram allows 2,200 characters in a caption and shows about 125 before the fold. Everything that matters has to be in that first line and a half.
YouTube allows 100 characters in a title, but search, suggested and mobile each cut it far sooner. Here is where each surface truncates.
