Why not just use CSS letter-spacing?

CSS letter-spacing only works in styled HTML. Plain-text contexts like chat apps, SMS, plain-text emails, or terminal output have no CSS, so inserting literal space characters is the only way to get a similar visual effect.

Does it add spaces around existing whitespace too?

Yes, spacing is inserted between every character in the text, including between words, so existing single spaces become wider gaps too.

Does the effect survive being posted?

The spaces are real characters, so they survive anywhere plain text does. Some platforms collapse runs of whitespace when rendering, though, in which case a spacing value above one may still display as a single space.

Text Spacing Increaser - Add Space Between Letters

Overview

Introduction

Spacing out text letter by letter for a stylized, widened look is a common trick in chat messages and social posts, but doing it by hand means retyping every character with spaces in between.

This tool automates it, and runs entirely client-side, so nothing you paste is ever uploaded to a server.

What Is Text Spacing Increaser?

A text-spacing tool that inserts a chosen number of extra space characters between every character of your input, simulating letter-spacing in plain text.

It's part of this site's String Tools collection and works entirely in your browser.

How Text Spacing Increaser Works

The tool splits the input into individual characters and rejoins them with a string of N spaces (N is your chosen spacing amount) inserted between each pair.

The transformation happens synchronously in JavaScript the moment you type or change the spacing amount, with no network round trip involved.

When To Use Text Spacing Increaser

Use it when you want a widened, spaced-out look for a message, banner, or title in a context that doesn't support CSS letter-spacing.

It's handy for stylizing plain-text headers in emails, chat apps, or code comments.

Often used alongside String Repeater and Whitespace Trimmer.

Features

Advantages

Adjustable spacing amount, not just a fixed single space.
Works in any plain-text context, no CSS or HTML required.
Splits by code point rather than by index, so an emoji is spaced out as a single unit instead of having its halves pulled apart.

Limitations

Very long text becomes dramatically longer, which can be unwieldy to read or paste elsewhere.
Not reversible without knowing the original spacing amount, since normal single spaces between words also get widened.

Examples

Widening a short word

Input

HELLO

Output

H E L L O

With a spacing of 1, a single space is inserted between each letter.

Best Practices & Notes

Best Practices

Use a small spacing value like 1 or 2 for readability; large values can make text hard to scan.
Preview the result before pasting into a space-constrained field like a title or username.
Check the resulting character count before posting, since the output grows by roughly the spacing value multiplied by the original length.

Developer Notes

The implementation uses Array.from(input) rather than a plain string index loop, so multi-byte Unicode characters (like emoji or accented letters) are split correctly instead of being broken apart by surrogate pairs.

Text Spacing Increaser Use Cases

Stylizing a plain-text banner or header
Widening a short word or acronym for emphasis in chat
Creating a spaced-out visual effect for social media posts

Common Mistakes

Applying a large spacing value to long paragraphs, producing unreadable output.
Expecting the effect to be reversible with a simple find-and-replace.

Tips

Combine with Text Spacing Normalizer afterward if you need to undo the effect and get back to single spaces (note this collapses all runs, not just the ones you added).
Existing spaces are spaced out too, so gaps between words widen faster than gaps between letters and word boundaries stay visible.
