Measuring your canvas accurately is the first step to selecting the perfect floater frame that makes your artwork appear to float within its borders. For standard floater frames, you'll measure your canvas's dimensions and then add a specific amount to determine the required frame size.
Here’s a simple guide on how to measure your canvas and calculate the correct size for a standard floater frame:
Step-by-Step Canvas Measurement Guide
Before calculating the frame size, you need precise measurements of your canvas.
Measure Canvas Width
- Use a reliable measuring tape.
- Measure the distance from the left edge to the right edge of the canvas. For stretched canvases, measure from the outer edge of the wood stretcher bar frame.
- Note down this measurement accurately.
Measure Canvas Height
- Measure the distance from the top edge to the bottom edge of the canvas. Again, measure from the outer edge of the stretcher bar.
- Note down this measurement.
Measure Canvas Depth
- Measure the thickness or depth of the canvas from the front surface to the back edge. This is crucial as floater frames are designed for specific canvas depths (e.g., 3/4", 1.5", 2").
- Note down this measurement. Ensure the frame you choose is compatible with your canvas depth.
Calculating Your Floater Frame Size
Once you have your canvas dimensions, you can determine the frame size using the standard rule for floater frames.
According to standard practices: When using standard floaters, add 1/2” to the width and height of the artwork when determining the frame size. This will achieve the effect of art floating within the walls of a frame by providing a 1/4” space between the edges of the artwork and walls.
Applying this rule:
- Required Frame Width: Your Canvas Width + 1/2 inch
- Required Frame Height: Your Canvas Height + 1/2 inch
This calculation ensures there is a 1/4-inch space all the way around your canvas, creating the desired "floating" effect when viewed from the front.
Example Measurement and Calculation
Let's say you have a canvas with the following measurements:
| Canvas Dimension | Measurement | Calculation for Frame Size | Required Frame Size |
|---|---|---|---|
| Width | 24 inches | 24" + 1/2" | 24.5 inches |
| Height | 36 inches | 36" + 1/2" | 36.5 inches |
| Depth | 1.5 inches | Select frame profile based on this | N/A for opening size |
In this example, you would need a floater frame with an interior opening size of 24.5 inches by 36.5 inches, designed to accommodate a 1.5-inch deep canvas.
Important Considerations
- Verify Frame Specifications: While adding 1/2" is standard for a 1/4" float, always double-check the specifications of the specific floater frame you plan to purchase. Some frames might have a different standard float space.
- Canvas Consistency: Ensure your canvas edges are relatively straight and the dimensions are consistent across the piece for the best fit and appearance.
By accurately measuring your canvas and applying the simple rule of adding 1/2 inch to the width and height for the frame size (to achieve a 1/4" float), you can confidently select the right floater frame to beautifully display your artwork. Remember to also match the frame's depth capacity to your canvas depth.
