Standard washers and dryers typically have the following widths:

• Full-size washers and dryers, whether front load or top load, are generally about 27 inches (approximately 68.6 cm) wide

• Compact washers and dryers designed for smaller spaces usually measure around 24 inches (about 61 cm) wide

• Washer-dryer combination units, which combine both functions in one appliance, tend to be narrower, with a standard width of about 60 cm (approximately 23.6 inches)

So, for most standard full-size washers and dryers, expect a width close to 27 inches, while compact and combination units are closer to 24 inches or 60 cm wide.
