What is the difference between housewife and Oxford pillowcases?

A housewife pillowcase fits snugly around the pillow with an internal flap. An Oxford pillowcase has a flat border (flange) around the edge, typically 5cm wide, giving a more decorative look.

What are standard UK pillow sizes?

Standard UK pillow: 75x50cm. King size pillow: 90x50cm. Euro square: 65x65cm. These are the pillow dimensions; the case is cut with allowances for seams and tuck-in.

How long should the tuck-in flap be?

A tuck-in flap of 15-20cm keeps the pillow inside without buttons or a zip. This flap folds inside the case and holds the pillow end. A shorter flap may allow the pillow to poke out.

What fabric works best for pillowcases?

Cotton percale (200+ thread count) or cotton sateen are traditional choices. Linen gives a relaxed look. Use fabric at least 150cm wide to cut pillowcases efficiently. Pre-wash all fabric before cutting.

How We Calculate This

A pillowcase is cut as one long piece that wraps around the pillow with a tuck-in flap. Oxford style adds an extra border around the edges.

The formula

Cut width = Pillow height + (Seam × 2)

Housewife length = Pillow width × 2 + 20cm tuck + Seams

Oxford length = Housewife length + Border × 2
