YouTube Shorts title length and character limits
By the KeyMo team · Updated
A YouTube Shorts title can be up to 100 characters. The description limit is 5,000 characters in YouTube Studio help, though the YouTube Data API documents 5000 bytes. YouTube's pages do not say how many title characters show before truncation, or set a limit for on-screen caption text.
The limits YouTube states, as of 11 October 2026
| Field | Limit | Where it is stated |
|---|---|---|
| Title | 100 characters; invalid characters not allowed | Shorts creation help and Studio upload help |
| Title (API) | 100 characters; all valid UTF-8 except < and > | YouTube Data API reference |
| Description | 5,000 characters; invalid characters not allowed | Studio upload help |
| Description (API) | 5000 bytes; all valid UTF-8 except < and > | YouTube Data API reference |
| Tags (API) | 500 characters in total, commas counted | YouTube Data API reference |
| Hashtags | More than 60 on one video and YouTube ignores all of them | Hashtag help |
| Hashtags shown | Up to three from the description appear by the title | Hashtag help |
What YouTube does not state
- How many characters of a title are visible before it is cut off. No number is printed.
- A character limit for text shown on the video. Captions burned into a Short are part of the picture, not a metadata field, so the pages set no limit for them.
- A minimum title length.
A worked count
Take the title Why most podcast clips lose people in three seconds. It is 51 characters, spaces included, which leaves 49 under the limit. Count spaces and punctuation, because they use characters too. Our caption character counter does the counting for you.
The description rule has a catch for non-English text. Studio help says 5,000 characters; the API says 5000 bytes. In UTF-8, a letter outside basic Latin, such as a Hindi letter, takes more than one byte, so an API upload can fit fewer characters than a Studio upload. If you publish through the API, count bytes.
Titles for clips cut from a longer video
A KeyMo clip is scored out of 10 and comes with a one-line reason, which is a handy starting point for the hook in your title. You type the title in YouTube when you post the exported clip, and the 100-character cap applies there. Clip length matters too; see the Shorts length limits.
