Practical tools for measured work
Circle and oval template
Generate repeated circles or ellipses at physical dimensions with centre marks and tiled PDF/SVG export.
Calculate the layout, check the diagram, then print the result for the shop or jobsite.
How it works
Enter a circle diameter or ellipse width and height in millimetres. A 6.4 cm circle is 64 mm in diameter. Repeat the outline in a grid with a chosen gap and optional centre crosses. Large layouts tile across PDF sheets at actual size; SVG keeps physical dimensions for further editing.
Current-input example
The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.
- Outline shape
- Circle
- Diameter
- 64 mm
- Number of outlines
- 1
- Layout columns
- 1
- Gap between outlines
- 5 mm
- Centre marks
- On
- Paper size
- A4
- Orientation
- Portrait
Primary result: Outline width: 64 mm.
Before using the result
- Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
- Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
- When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.
Limitations
Outlines are 5–1000 mm, with 1–40 copies and a total layout no larger than 1200 mm in either direction. Ellipses use a 720-segment approximation with maximum geometric deviation below 0.005 mm. Print at 100% and measure the 10 mm square. Stroke width, printer accuracy and material cutting allowance are not added to dimensions.
Frequently asked questions
What should I verify before using this result?
Recheck the physical measurements, confirm that every input uses the displayed unit, and compare the result with the applicable drawing, product specification, code requirement or test piece.
Why might the finished result differ?
Real work can include thickness, kerf, seams, tolerances, hardware allowances, installation clearances or site conditions that are outside the calculation. The limitations section identifies the main exclusions for this tool.
