Bar length represents bytes. The physical sizes of devices are schematic; encoding and compression affect file sizes.

A little perspective

100 bytes is about 1.25 times the serialized header size of a Bitcoin block header.

Measurements, assumptions & sources +

100 bytes

Data: 100 B; definition.

Decimal kB, MB and GB use powers of 1,000. KiB, MiB and GiB use powers of 1,024. The content of a file depends on encoding and compression.

NIST — SI conversion factors

Bitcoin block header

Serialized header size: 80 B; definition.

The serialized Bitcoin block header is defined as 80 bytes. This excludes transactions, network framing and any display encoding.

Defined examples — our methodology

The marked serialized header size is calibrated. Unmeasured illustration details are representative.

Relative size
100 bytes is about 1.25 times the serialized header size of a Bitcoin block header. 100 bytes is approximately 25% greater than the serialized header size of a Bitcoin block header.

How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

Data size depends on encoding and compression; decimal GB and binary GiB are different units.
