What is in this file

49 numbered lines of plain English text, each prefixed with its line number and starting byte offset so truncation is easy to spot. A closing rule of "=" characters brings the file to the exact size.

Where 5 KB matters

A 5,120-byte file: larger than a cookie, smaller than a typical HTTP header limit. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Browser cookies	4,096 bytes per cookie	5 KB does not fit in one cookie.
Vite asset inlining	4 KB by default (assetsInlineLimit)	A 5 KB asset is emitted as a separate file rather than inlined as base64.
nginx and Apache request headers	8 KB per header line by default	5 KB fits; the 10 KB sample does not.

Use this file for

Checking asset-inlining thresholds in bundlers
Checking encoding handling
Testing line-ending normalisation

Testing notes for TXT

Line endings change the byte count: converting LF to CRLF adds one byte per line, which breaks checksum comparisons.
An empty or whitespace-only file is still a valid text file and is worth a test of its own.

Download from the command line and verify

Fetch the file with curl, then compare its checksum with the SHA-256 value above.

curl -o sample-txt-5kb.txt 'https://sampletestfiles.com/downloads/txt/sample-txt-5kb.txt'
sha256sum sample-txt-5kb.txt     # Linux
shasum -a 256 sample-txt-5kb.txt # macOS

On Windows, run Get-FileHash sample-txt-5kb.txt -Algorithm SHA256 in PowerShell. A matching value proves that the download is complete and unaltered.

Questions about this file

Is this file exactly 5 KB?: Yes. It is 5,120 bytes, which is 5 KB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
What is inside the 5 KB TXT file?: 49 numbered lines of plain English text, each prefixed with its line number and starting byte offset so truncation is easy to spot. A closing rule of "=" characters brings the file to the exact size.
Which encoding do the text samples use?: The sized samples use only ASCII characters, which makes them valid UTF-8, ASCII and Latin-1 at once. A separate multilingual sample covers non-ASCII text.
