❓ Frequently Asked Questions
▶What are the different ways to measure text size and when should I use each?
Character Count:
text.length; // JavaScript code units
[...text].length; // Unicode code points
// Grapheme clusters (visual characters)
new Intl.Segmenter('en', { granularity: 'grapheme' })
.segment(text).length;Byte Size:
new Blob([text]).size; // UTF-8 bytes
new TextEncoder().encode(text).length; // UTF-8 bytes
// Specific encoding
function getByteSize(text, encoding = 'utf-8') {
return new Blob([text], { type: `text/plain;charset=${encoding}` }).size;
}Word Count:
(text.match(/\b\w+\b/g) || []).length;▶How do I calculate accurate byte sizes for different encodings?
UTF-8 vs UTF-16:
const text = 'Hello 世界';
// UTF-8 (variable 1-4 bytes per character)
const utf8 = new TextEncoder().encode(text).length;
// Result: 11 bytes
// UTF-16 (2 bytes per code unit)
const utf16 = text.length * 2;
// Result: 16 bytesDatabase VARCHAR Limits:
// MySQL VARCHAR(255) is 255 bytes in UTF-8
function fitsInVarchar(text, limit = 255) {
return new TextEncoder().encode(text).length <= limit;
}SMS Message Size:
function getSMSSegments(text) {
const bytes = new TextEncoder().encode(text).length;
// GSM-7: 160 chars, UCS-2: 70 chars per segment
const isUCS2 = /[^\x00-\x7F]/.test(text);
const limit = isUCS2 ? 70 : 160;
return Math.ceil(bytes / limit);
}▶How do I estimate reading time and visual size of text?
Reading Time:
function estimateReadingTime(text) {
const words = (text.match(/\b\w+\b/g) || []).length;
const wpm = 200; // Average reading speed
const minutes = Math.ceil(words / wpm);
return `${minutes} min read`;
}Visual Width (Canvas):
function measureTextWidth(text, font = '16px Arial') {
const canvas = document.createElement('canvas');
const ctx = canvas.getContext('2d');
ctx.font = font;
return ctx.measureText(text).width;
}Line Count Estimation:
function estimateLines(text, charsPerLine = 80) {
return Math.ceil(text.length / charsPerLine);
