Scale Bar Generator
Make a true-size SVG scale bar from a drawing scale, a real length and one to ten labelled segments.

How do I make a scale bar for a drawing?
Enter the drawing ratio and the real length represented by the complete bar.
Choose the real-length unit and a segment count from one to ten.
Generate and download the SVG, preserve its physical dimensions when placing it, and verify the printed result.
How is a scale bar’s length worked out?
This scale bar generator makes a labelled SVG scale bar, sometimes called a graphic scale, at true size for any drawing scale, ready to place on a drawing or map layout.
The real length divided by the scale denominator gives the on-paper length for a 1:n ratio. A 10 m bar at 1:50 is 200 mm long. The download adds margins outside the bar and divides its length into equal labelled segments. Tick values are rounded to three significant figures for display; the bar geometry itself is not rounded.
How Xenmark makes it easy to make a scale bar for a drawing
A scale bar sized in real millimetres
The SVG states its width and height in millimetres, so a 10 m bar at 1:50 downloads as a 200 mm bar with a 5 mm margin at each end.
Nothing you enter leaves this tab
What you type is held and worked on in this tab only. There is no upload, no account and no server for it to go to.
One to ten labelled segments
Divide the bar into as many as ten equal segments, alternating black and white, with a value under every tick and the unit printed beneath the bar.
Crowded labels are refused before download
Segments narrower than 12 mm, or tick values that would run into each other, are refused with a reason instead of producing a scale bar nobody can read.
A plain vector file for your layout
The download is one small SVG built from rectangles, lines and text, ready to place in layout or drawing software that accepts SVG. Labels are live text set in Arial or the nearest sans-serif available.
Nothing to install
It runs in the browser you already have. There is no plug-in, no desktop application and no sign-up to get through first.
Limitations
What this tool does not do, stated up front.
The bar is accurate only when it retains its calculated dimensions through placement, export and printing.
Bars shorter than the labels need, or longer than 500 mm on paper, are refused, as are segments narrower than 12 mm. The screen preview is not a calibrated ruler.
A scale bar does not verify that the source drawing has the correct scale or satisfies project requirements.
Questions
How many segments can the bar have?
Choose one to ten. The generator also checks whether the selected physical length, up to 500 mm on paper, provides enough space for the labels.
How should I print the scale bar?
Keep the SVG at its stated millimetre dimensions and print at Actual size (100%) with Fit to page disabled. Measure the output to confirm its size.
How long is a 10 m scale bar at 1:50?
200 mm. Divide the real length by the scale: 10,000 mm ÷ 50 = 200 mm on paper.
Why did Xenmark build a free scale bar generator?
Xenmark AS is a Norwegian software company building browser-based drawing review tools for owners, consultants, operators and other teams that receive and review technical drawings. Those teams work with drawing numbers, revisions and client details that are not always meant to leave the office. So these everyday tools are free and run entirely in your browser: no account, and nothing you enter is sent anywhere. You can check that yourself — open your browser’s network tab, generate a scale bar, and watch nothing leave. What this tool cannot do is listed under Limitations above.

Beyond the free tools
Reviewing the drawings, not just handling the files?
Xenmark is affordable PDF markup and structured drawing review in the browser. Invite reviewers, pin numbered comments on the sheet, track every one by author and status, and export a clean PDF and Excel when the review is done. Unlike these tools, a review is shared, so its drawings are uploaded to your Xenmark project.
Free forever plan. Reviewers you invite never pay.
