How to use Scale a Vector
- 1. Paste your vectors. Enter one vector per line, for example (1, 2, 3). Each is scaled independently, so different-length vectors can be listed together.
- 2. Set the scale factor. Choose Factor, the number every component is multiplied by. Use a value greater than 1 to enlarge, between 0 and 1 to shrink, or negative to also flip direction.
- 3. Choose the wrap style. Pick Parentheses, Brackets, or None for how the scaled vector is displayed, matching the notation used elsewhere in your document.
- 4. Copy the scaled vectors. The output pane shows every vector resized by your factor. Copy it into a graphics project, physics calculation, or spreadsheet.
When to use Scale a Vector
Scale a Vector shrinks or enlarges one or more vectors by a chosen factor, multiplying every component the same way. Use it whenever you need a vector resized to a specific proportion of its original magnitude.
- Resizing an arrow in a technical diagram. You are drawing a force or displacement diagram and need to shrink an oversized vector so its arrow fits proportionally alongside the others on the page.
- Adjusting a camera zoom vector in a game. A game prototype uses a direction vector to control camera movement speed, and scaling it by a factor lets you test faster or slower movement without changing the underlying direction logic.
- Converting units of a measurement vector. A vector of measurements is in the wrong unit scale, for example millimeters instead of centimeters, and scaling by the conversion factor fixes the whole vector at once.
- Testing edge cases in a scaling function. You are validating a vector math library's scale function with factors like 0, negative numbers, and fractions, and want known-correct scaled results to check your implementation against.

About the Scale a Vector tool
Scale a Vector runs as plain JavaScript in your browser tab, with no server behind it. Shrink or enlarge by a factor. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Math Tools section, 234 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Factor and Wrap, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Scale a Vector free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
