TLDR Meaning: Quick Answer

TLDR means too long; didn't read. Five quick examples:

Definition and Origin

TLDR (or TL;DR) stands for too long; didn't read. It's a label for a short summary of a long message — either a polite one-liner you add at the end, or a blunt reply when someone dumps a wall of text.

TL;DR grew out of early-2000s forums like Something Awful and Reddit, where users would flag lengthy posts with “too long; didn't read.” Over time it flipped from an insult into a helpful convention: writers now add their own “TL;DR” summary at the end of long posts.

How to Use TLDR in Chats and Texts

““TL;DR — the meeting is moved to Thursday.””
““I wrote a whole thing, but tl;dr: I'm not going.””
““Tl;dr the new policy only affects contractors.””

Variations and Related Terms

TL;DR — the same thing with a semicolon — the classic, slightly more formal spelling
TLDW — too long; didn't watch — for videos
TLDR version — the short version of a story or post

Social Media and Meme Usage

Reddit popularized TL;DR as a courtesy: a good long post ends with a one-line summary. In work chats and email threads, adding your own TL;DR is a genuinely useful, respected move — it saves everyone time.

Keep the summary to one or two sentences — that's the point.
