عدّاد الأحرف

What is عدّاد الأحرف?

A character counter measures the length of input text in characters (with and without spaces), words, sentences, and paragraphs. These counts are essential when content must fit a fixed limit — meta descriptions, tweets, SMS messages, database fields, and form inputs all have character caps. The counter updates instantly as the user types, with no upload.

How It Works

The tool reads the input string and computes .length for the total character count (including spaces). The without-spaces count subtracts all whitespace characters. Words are counted by splitting on whitespace sequences and discarding empty fragments. Sentences are approximated by terminal punctuation (. ! ?) followed by a boundary. Paragraphs are split on double newlines. All metrics are computed in a single O(n) pass locally.

Common Use Cases

• Writing SEO titles and meta descriptions — stay under 60 and 160 character limits
• Composing tweets or SMS — fit within 280 or 160 character caps
• Filling form fields with limits — monitor input against a maxlength in real time
• Checking database column capacity — confirm text fits a VARCHAR(n) before insert

Technical Details

Character count uses the string's .length property (UTF-16 code units; surrogate pairs count as 2). For accurate Unicode code-point counts, the tool iterates with a code-point iterator. Word splitting uses a Unicode whitespace regex. Sentence detection is heuristic and may miscount abbreviations. All processing is local and runs in O(n) time.
