Chamevo can display element dimensions and a ruler on the canvas so customers understand the physical size of their design. This is helpful for products where exact dimensions matter — signs, labels, business cards, and any print product.

Enable the size tooltip

1. Go to Chamevo → Settings → General → Display.
2. Enable Size Tooltip.

When a customer selects an element on the canvas, a tooltip shows the element's width and height in the selected unit of measurement.

Set the unit of measurement

1. Go to Chamevo → Settings → General → Display.
2. Find Unit of Measurement.
3. Select the unit:
   • Pixel — raw pixel dimensions.
   • Millimeter — default, common for print products.
   • Centimeter — alternative metric unit.
   • Inch — for US/UK-based print workflows.

The selected unit applies to both the size tooltip and the canvas ruler. The conversion from pixels to physical units is based on the DPI set in the product's print profile.

Configure the ruler

The ruler provides a visual scale reference on the canvas.

1. Go to Chamevo → Settings → General → Actions.
2. Find the Ruler section.
3. Set Ruler Position:
   • Canvas — the ruler appears along the canvas edges.
   • Around Printing Box — the ruler appears around the defined print area. This requires a printing box set in the product view.
4. Optionally enable Always Show Ruler to keep the ruler visible at all times. When disabled, customers toggle it using the Ruler action in the toolbar.

Check your setup

1. Open a product on the frontend.
2. Select an element and verify the size tooltip shows dimensions in the correct unit.
3. Toggle the ruler (or verify it is always visible) and check that it displays the correct scale.
4. Upload an image and verify the tooltip updates to reflect the image's size on the canvas.

Troubleshooting

Tooltip shows pixel values instead of physical units

• Verify the Unit of Measurement is set to Millimeter, Centimeter, or Inch — not Pixel.
• Check that the product has a print profile with a DPI value set. Without DPI, the conversion to physical units cannot be calculated.
