LED strip profiles, also known as LED strip aluminum channels or LED strip extrusions, come in various sizes depending on the specific manufacturer and model. The most common sizes are:

1. Width: LED strip profiles typically have widths ranging from 10mm to 20mm. This width is designed to accommodate the standard size of LED strips available in the market, which are usually 8mm to 12mm wide.

2. Height: The height of LED strip profiles varies greatly and can range from as low as 4mm to as high as 20mm or more. The height is determined by the depth required to house the LED strip and any additional components such as diffusers or lenses.

3. Length: LED strip profiles are typically sold in standard lengths, such as 1 meter (3.28 feet) or 2 meters (6.56 feet). However, some manufacturers may offer custom lengths upon request.

It's important to note that these sizes are general guidelines, and the availability of specific sizes may vary from manufacturer to manufacturer. If you are looking for LED strip profiles, it is recommended to consult the product specifications or contact the manufacturer directly for accurate information on available sizes.
