A size 27 in women's jeans generally corresponds to a waist measurement of about 26 to 27 inches and hip measurement around 36 to 37 inches. This size typically aligns with a US women's size 4 or sometimes 2-4 depending on the brand. It is considered a small size in most sizing charts. In European sizing, a size 27 jeans is usually equivalent to an EU size 34. Here are some detailed points from various sources:

• Waist: 26-27 inches
• Hips: 36-37 inches
• US size equivalent: about 4 (sometimes 2-4)
• Considered small size
• EU size equivalent: 34

This means if you wear a size 27 jeans, you are likely fitting into a small or size 4 in US sizing

. Because sizing can vary slightly by brand and style, measuring your waist and hips and consulting the specific brand's size chart is recommended for the best fit.
