King Size Deep Fitted Sheet FAQs

What dimensions are a king size deep fitted sheet?

 A standard king size deep fitted sheet typically measures 150 cm wide (59 inches) by 200 cm long (79 inches) with a depth of 30-40 cm (12-16 inches) to accommodate thicker mattresses. Extra deep fitted sheets can have a depth of up to 50 cm (20 inches). Always check your mattress depth to ensure the best fit

Will these king size sheets fit extra deep mattresses or mattress toppers?

 King size deep fitted sheets with a depth of 30-40 cm (12-16 inches) can fit most deep mattresses, but for extra deep mattresses or thick mattress toppers, you'll need extra deep fitted sheets with a depth of up to 50 cm (20 inches) for a perfect fit. Always measure your mattress including the topper to ensure the right sheet depth.
