What is a Text Size Calculator?
A Text Size Calculator determines the exact byte size of your text across different character encodings. This is crucial for developers working with databases, APIs, or any system with size constraints.
Frequently Asked Questions (FAQ)
What encoding sizes does it show?
It shows sizes in UTF-8 (web standard), UTF-16 (Windows/Java standard), and ASCII encoding.
Why do different encodings have different sizes?
UTF-8 uses 1-4 bytes per character, UTF-16 uses 2-4 bytes, and ASCII uses 1 byte (for English characters only).
What is this useful for?
It helps developers estimate storage, API payload sizes, database column widths, and network transfer sizes.
