What is in this file

A FeatureCollection of 4 features around real cities, mostly points with a line string and a polygon in every ten. A "padding" foreign member, which RFC 7946 permits, brings the file to the exact size.

Features	4
Geometry types	Point, LineString, Polygon
Coordinate order	Longitude, latitude (WGS 84)
Encoding	UTF-8 (ASCII characters only)

Where 1 KB matters

The smallest practical test file: 1,024 bytes, small enough to travel in a single network packet. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Ethernet	1,500 bytes (typical MTU)	A 1 KB payload fits in one packet with its headers.
Browser cookies	4,096 bytes per cookie	1 KB is well inside the limit; the 5 KB sample is over it.

All 1 KB sample files

Use this file for

Smoke tests in CI that must run in milliseconds
Testing map layers and spatial queries
Checking coordinate-order handling

Testing notes for GeoJSON

Swapped latitude and longitude put points in the wrong hemisphere or the ocean. Test with locations you can recognise.
Polygon rings must be closed, with the first and last positions identical.

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-geojson-1kb.geojson 'https://sampletestfiles.com/downloads/geojson/sample-geojson-1kb.geojson'
sha256sum sample-geojson-1kb.geojson     # Linux
shasum -a 256 sample-geojson-1kb.geojson # macOS

Questions about this file

Is this file exactly 1 KB?: Yes. It is 1,024 bytes, which is 1 KB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
What is inside the 1 KB GeoJSON file?: A FeatureCollection of 4 features around real cities, mostly points with a line string and a polygon in every ten. A "padding" foreign member, which RFC 7946 permits, brings the file to the exact size.
Where are the sample features located?: Near sixteen real cities on six continents, with small random offsets, so the result is easy to check on a map.
