When an SVG opens at the wrong physical size in xTool Studio, measure a known object before changing the design. xTool documents an SVG Import Settings → DPI control that affects the dimensions shown on Canvas. It also documents an option to auto-scale an image that is too large for the canvas. A 50 mm reference square or a slot width you know gives you a way to distinguish those causes from a file that was already exported at the wrong size.
Save the original SVG, import a copy, and write down the source dimension and Studio's displayed width. Do not use the apparent size on screen as a ruler: zoom and a machine's work area affect what you see, while the width field gives you a number to compare.
Make one trustworthy measurement
- Choose an object with a known intended dimension. A 50 mm square, a 3 mm slot, or a documented pattern width is better than the whole drawing if its outer boundary includes hidden shapes or large blank margins. Keep units explicit.
- Check the source file in the program that created it. Record the selected object's width and the SVG's page size or viewBox if available. A PDF or screenshot of the intended measurement is useful for comparison, but it is not a substitute for the editable vector.
- Import the SVG into a new Studio project. Select the same reference object and read its numerical width. For example, if a 50 mm square reads 37.5 mm, that is a uniform 0.75 scale factor worth investigating; if width and height differ by different factors, look for a nonuniform transform or resized selection instead.
- Do not cut yet. An onscreen scaling discrepancy can make slots too tight, joints too loose, or a design exceed the machine's available area. Correct and re-measure the file before setting material or processing parameters.
Check Studio's SVG import DPI
xTool's Import & Parse Vectors guide, updated 27 February 2026, says the SVG import DPI value determines rendering size on Canvas. Its example: an SVG exported at 72 DPI will initially match the source dimensions when imported with a 72 DPI setting; importing it at 96 DPI makes it appear smaller. xTool's software settings guide places this control under SVG Import Settings.
Compare the export DPI used by the originating app with Studio's SVG import setting. Change the import setting on a copy of the project and import again, then re-measure the known object. Do not repeatedly scale an already imported selection by eye. A 72-to-96 mismatch explains a 75% dimension in xTool's example, but the actual cause of another file has to be measured.
SVG is vector artwork, so this setting is about interpreting imported dimensions, not making a cut line sharper by increasing a raster image's resolution. If the size is correct but curves are jagged or paths are missing, use xTool's separate vector-quality or import-failure guidance instead.
Rule out automatic fit-to-canvas scaling
xTool's software settings also offer three treatments for an import larger than the canvas: ask each time, auto-scale it, or keep its size. If the imported file is unusually large, auto-scale can make its displayed width smaller even when the SVG's original dimension was intentional. Try the ask each time choice and inspect the import prompt, or keep original size for a diagnostic re-import. Then compare the reference measurement again. Do not assume every small import was auto-scaled; this option applies when the artwork exceeds the canvas.
These settings are distinct from xTool's DXF Import Settings → Units. A DXF unit mismatch can be solved in that menu, but using a DXF units control for an SVG sizing problem can send you down the wrong path. Makerfern's Silhouette DXF scaling guide is also a different application and file type.
When the dimensions are still wrong
Check whether the selected Studio object is the reference shape or a group containing invisible or off-page objects. Look for a transform or extra bounding artwork in the SVG source. Re-export the original with an explicit physical page size and a known reference square, then import that clean copy. If the square measures correctly while the original design does not, the problem is more likely in the source document or its export. If both shrink by the same factor, revisit the import settings.
For a slot-based project, measure the slot after import and again after any global resize. If you need to change a 3 mm slot to fit measured 3.2 mm stock, edit that geometry deliberately; do not use the whole-design DPI setting as a material-thickness adjustment. The laser kerf and joint guide covers cut-fit measurements after the file's scale is right.
Makerfern's browser-local SVG checker can inspect an SVG's structure, and image-to-DXF converter can prepare suitable artwork for laser/CNC workflows. Neither sets Studio's import DPI or validates physical machine output. See how Makerfern processes files and its free and Pro features for the tool scope. For a vector that imports with missing or merged parts rather than the wrong size, read the xTool SVG auto-merge guide.

Keep a known-size reference in the file, align the import setting with the export, and re-import a copy. Only after the reference measures correctly should you set processing parameters or make a small material test.
