Hex Encoding Size Estimator
Plan hex representation length with optional separators.
Your inputs
Calculation results
Formula & assumptions
Hex digits = 2 × bytes; within-line separators and LF line endings are counted separately.
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.
Compare your scenarios
Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Hex Encoding Size Estimator
Plan hex representation length with optional separators.
- Enter binary bytes, separator length, bytes per line using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Binary bytes: 256 bytes Separator length: 1 characters Bytes per line: 16 bytes Hex digits: 512 Lines: 16 Characters with separators and LF: 767
Questions & answers
What does Hex Encoding Size Estimator calculate?
Plan hex representation length with optional separators.
Which units should I enter?
Binary bytes uses bytes. Separator length uses characters. Bytes per line uses bytes. Convert values to these units before calculating.
Which formula does it use?
Hex digits = 2 × bytes; within-line separators and LF line endings are counted separately.
What does the included example show?
Binary bytes: 256 bytes; Separator length: 1 characters; Bytes per line: 16 bytes. Result: Hex digits = 512; Lines = 16; Characters with separators and LF = 767.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
