Text Line Padding

Free online tool to pad text lines with characters to reach a specified length.

Tool Guide

Introduction

An online text line padding tool — a typesetting aid for aligning and fixing the width of multiline data. It supports padding the left, right, or both (centered) sides of each line of text with a specific length of spaces or custom characters, to meet data alignment or fixed field format requirements.

Key Features

  1. Smart multi-directional padding: Supports three basic padding directions — "pad left (prefix padding)," "pad right (suffix padding)," and "centered symmetric alignment."
  2. Precise width control: Freely slide or type to set the total target width of each line. If the original line is too short, it's automatically padded with the set character; if it's too long, you can choose to keep or truncate it.
  3. Data cleaning and typesetting: For code snippets that need aligned printed output, or roster fields written to fixed-width database files, this tool delivers ultimate typesetting speed.

How to Use

  1. In the input area above, paste the multiline original string you want to align.
  2. Set the total target width you need per line (e.g. 20 characters), enter the character to pad with in the padding-character box (default is a space), and choose the padding direction.
  3. Click "Run Text Padding", and the system will output the aligned, formatted character view on the right/below — click to copy or download directly.
