# Hong Kong Pillow & Pillowcase Size Guide 2026-09-18 Buying a pillowcase sounds simple until the measurements do not match. One brand calls a pillow “standard”, another sells 50 x 75 cm, another uses 50 x 80 cm, and a Japanese-style pillow may be considerably smaller. Unlike mattresses, there is no single pillow dimension used by every retailer in Hong Kong. The safest rule is therefore simple: check the measurements in centimetres rather than relying only on names such as Standard, Queen or King. Then consider the pillow’s thickness and construction, because a highly filled or gusseted pillow can occupy more space inside a case than a flatter pillow with the same face dimensions. **QUICK ANSWER** There is no single mandatory standard pillow size in Hong Kong. Around 50 x 75 cm to 50 x 80 cm is a common larger adult pillow range among major retailers, while 43 x 63 cm and specialty sizes are also widely sold. Always compare the exact pillow and pillowcase dimensions before buying across brands. ## Pillow Size vs Pillow Height: What Is the Difference? Pillow size normally describes the rectangular footprint of the pillow—its two face dimensions. Pillow height, also called loft, describes how thick or tall the pillow is before or while it is being used. These are separate specifications. For example, a 50 x 75 cm pillow can be offered in a low and high version without changing the pillowcase footprint. Hush Home’s [**Loft Pillow™**](https://www.hushhome.com/products/loftpillow) is 50 x 75 cm in both versions, but is available at 12 cm and 15 cm nominal heights. This distinction matters because pillow height affects neck positioning and sleep feel, while pillow length and width mainly determine how much surface area you have and which pillowcase will fit. If you are deciding how high your pillow should be, use Hush Home’s [**Pillow Height Guide**](https://www.hushhome.com/blogs/sleep-products-guide/pillow-height-guide-how-to-choose-the-right-pillow) rather than choosing based on case size. ## Common Pillow Sizes You May See in Hong Kong Pillow Size Where You May See It What to Know **50 x 75 cm** Common contemporary adult rectangular size; used by Zara Home Hong Kong and selected Hush Home pillows. A familiar hotel-style proportion. Hush OnePillow™ and Loft Pillow™ use this face size. **50 x 80 cm** Common among IKEA Hong Kong adult pillows and pillowcases. Slightly longer than 50 x 75 cm. A matching 50 x 80 cm case is the safest fit. **43 x 63 cm** Available across several MUJI Hong Kong pillows. Shows why not every adult pillow in Hong Kong follows a 50 x 75–80 cm format. **Specialty sizes** Contour memory foam, cervical, travel and ergonomic pillows. May require a dedicated shaped pillowcase rather than a conventional rectangular case. ## What Do Standard, Queen and King Pillow Sizes Mean? These names are particularly common on imported bedding, but they are not a reliable substitute for centimetre measurements in Hong Kong. In the commonly used US sizing system, Standard is approximately 51 x 66 cm, Queen approximately 51 x 76 cm and King approximately 51 x 91 cm. Other countries and individual brands may use the same words differently. **Treat the label as a category name and the centimetres as the real specification.** If a case says “Standard/Queen 51 x 77 cm”, the 51 x 77 cm measurement is more useful than trying to decide whether your pillow is officially a Standard or Queen. ## What Size Should a Pillowcase Be? A pillowcase does not always need to have exactly the same printed measurements as the pillow. A case is measured flat, while a filled pillow has depth and curves. Seams, closures, fabric stretch and how compressible the fill is all affect the final fit. For a conventional pillow, a pillowcase that is slightly larger than the pillow’s face dimensions is normal. Too small and the case can compress the pillow, make a soft pillow feel firmer or cause the opening to gape. Too large and excess fabric can bunch around the face or make the pillow look untidy. If you are buying the pillow and pillowcase from different brands, compare the two shorter dimensions with each other and the two longer dimensions with each other. For unusually thick or shaped pillows, also check the manufacturer’s stated compatibility rather than relying on length and width alone. ## Hush Home Pillowcase Size Hush Home’s adult pillowcase size is **51 x 77 cm**. The [**Egyptian Cotton Hotel Pillowcases™**](https://www.hushhome.com/products/pillowcases) are sold as Standard/Queen, while Hush Home’s bedding size guide lists its adult pillowcase at 51 x 77 cm. The [**Mulberry Silk Pillowcase™**](https://www.hushhome.com/products/mulberry-silk-pillowcase) is also 51 x 77 cm and uses an envelope enclosure. A 51 x 77 cm case sits very close to the common 50 x 75 cm hotel-style pillow format, while still providing a little room for seams and fullness. Hush Home states that its Mulberry Silk Pillowcase™ fits the Miracle Pillow™, OnePillow™, Loft Pillow™ and standard pillows. ## Hush Home Adult Pillow Size Reference Pillow Face Dimensions Height Pillowcase Notes [**Miracle Pillow™**](https://www.hushhome.com/products/miracle-pillow) 35 x 65 cm Adjustable to 12, 14, 16 or 18 cm Hush Home explicitly lists the 51 x 77 cm Mulberry Silk Pillowcase™ as compatible. [**OnePillow™**](https://www.hushhome.com/products/onepillow) 50 x 75 cm Adjustable below approximately 20 cm Very close match to the 51 x 77 cm adult pillowcase format. [**Loft Pillow™**](https://www.hushhome.com/products/loftpillow) 50 x 75 cm 12 cm or 15 cm Both height options use the same pillowcase footprint. [**Essence Memory Foam Pillow™**](https://www.hushhome.com/products/the-memory-foam-pillow) 60 x 40 cm Approximately 12 cm Compact solid-foam shape; compare actual measurements when buying third-party cases. This variety is intentional. Pillowcase fit and sleep support are related, but they are not the same decision. If you want to compare materials, heights and adjustability across the full range, see [**all Hush Home pillows**](https://www.hushhome.com/pages/pillows) or our [**Best Pillow Brands in Hong Kong comparison guide**](https://www.hushhome.com/pages/best-pillow-brands-hong-kong). ## Which Hush Home Pillowcase Should You Choose? ### Egyptian Cotton Hotel Pillowcases™ For everyday hotel-style bedding, the [**Egyptian Cotton Hotel Pillowcases™**](https://www.hushhome.com/products/pillowcases) provide a 51 x 77 cm Standard/Queen format in Hush Home’s Egyptian long-staple cotton bedding system. Each set contains two pillowcases. ### Mulberry Silk Pillowcase™ For shoppers who specifically want silk against the hair and skin, the [**Mulberry Silk Pillowcase™**](https://www.hushhome.com/products/mulberry-silk-pillowcase) uses the same 51 x 77 cm size with an envelope enclosure. Hush Home explicitly lists it as compatible with the Miracle Pillow™, OnePillow™, Loft Pillow™ and standard pillows. The better choice between cotton and silk is therefore mainly about material, feel, care and budget—not a different adult pillow size within Hush Home’s range. ## What Pillow Size Should You Use for a Single, Double, Queen or King Bed? Mattress size does not determine the pillow height you need, but it does affect how many pillows look and fit comfortably across the head of the bed. Hong Kong mattresses also use different widths from some overseas standards, so it is worth thinking in centimetres rather than copying an American bedroom-styling chart. Bed Width Practical Pillow Arrangement **3'0" Single / about 91 cm** One adult rectangular sleeping pillow is usually the cleanest arrangement. A 50 x 75 cm pillow leaves room at the sides. **4'0" Double / about 122 cm** One large pillow works for a solo sleeper. Couples will generally want one sleeping pillow each; two long hotel-style pillows may look visually full. **4'6" Full / about 137 cm** Two conventional adult pillows are a practical choice for couples. **5'0" Queen / about 152 cm** Two 50 x 75 cm hotel-style pillows create a natural visual fit across the bed. **6'0" King / about 183 cm** Two standard-sized adult pillows remain practical. Longer King pillows or decorative cushions are optional styling choices. **A King mattress does not require a King pillow.** Pillow length and width affect sleeping surface and bedroom styling, while pillow loft and support should be chosen around the sleeper. ## How to Measure Your Pillow Before Buying a Pillowcase 1. **Remove the existing pillowcase.** Measure the pillow itself rather than an old case, which may have shrunk, stretched or originally been larger. 2. **Measure the shorter face dimension.** Lay the pillow naturally on a flat surface without pressing it completely flat, then measure edge to edge. 3. **Measure the longer face dimension.** These first two measurements are the most important numbers for a conventional pillowcase. 4. **Note the pillow’s depth or loft.** A very thick pillow can need more fabric volume than a thin pillow, especially if it is memory foam, gusseted or heavily filled. 5. **Check the closure.** Envelope closures, zips and simple open-end cases behave differently. A secure envelope can help keep a slightly smaller pillow neatly inside the case. ## Will a 50 x 80 cm Pillowcase Fit a 50 x 75 cm Pillow? Usually, yes. The case is only 5 cm longer, so many conventional 50 x 75 cm pillows can sit inside a 50 x 80 cm case with a little extra fabric at the end. Whether the result looks neat depends on the closure and how full the pillow is. The opposite direction needs more caution. Putting a 50 x 80 cm pillow into a 50 x 75 cm case can compress the pillow or make the case difficult to close, particularly if the pillow is firm or heavily filled. ## Will a 51 x 77 cm Pillowcase Fit a 50 x 75 cm Pillow? Yes. This is a close dimensional match for a conventional pillow. The small difference allows space for the pillow’s fullness, seams and closure. Hush Home uses 51 x 77 cm for its adult pillowcases while the OnePillow™ and Loft Pillow™ are 50 x 75 cm. ## Does Pillowcase Size Affect Pillow Firmness? It can. A case that is much too tight can compress a soft or adjustable-fill pillow, reducing its ability to spread and making it feel firmer or taller. A very loose case does not usually change the support as much, but excess fabric may bunch and feel less comfortable. This is another reason not to force an oversized pillow into a smaller case simply because both products use the word “standard”. ## What About Pillow Protectors? A pillow protector sits between the pillow and pillowcase. It is designed to protect the pillow from moisture, body oils, dust and other everyday exposure. Because it adds another layer around the pillow, fit still matters. **The safest sequence is:** pillow → correctly fitting protector → pillowcase. If you use a bulky protector or one that is too small, it can change how easily the pillow slides into the outer case. Follow the protector manufacturer’s stated compatibility whenever available. ## Kids’ Pillows Use Different Sizes Children’s pillows should not be assumed to use adult pillowcase dimensions. Hush Home’s [**Little Organic Adjustable Kid Pillow™**](https://www.hushhome.com/products/kid-pillow) measures 50 x 30 cm at its base profile, with removable layers that increase height. Its dedicated [**Little Organic Duvet Cover & Pillowcase**](https://www.hushhome.com/products/baby-kid-duvet-cover-pillow-case) set uses a 40 x 58 cm pillow cover, while the [**Little Organic Pillow Protector™**](https://www.hushhome.com/products/baby-kid-pillow-protector) is 55 x 38 cm and is designed for children’s pillows up to that size. This is a good example of why a pillowcase is often intentionally larger than the pillow’s nominal face size. The extra fabric accommodates the pillow’s depth and changing profile while providing a usable closure. ## Common Pillowcase Size Mistakes - **Shopping by “Standard” alone:** different brands and countries can use the word for different measurements. Always check centimetres. - **Confusing pillow height with pillow size:** a 12 cm and 15 cm pillow can use the same case if their face dimensions are the same and the case has enough volume. - **Assuming your mattress size dictates your pillow size:** a King mattress does not require a King pillow. - **Forcing a large pillow into a small case:** an overly tight case can change the pillow’s feel and strain seams or closures. - **Ignoring specialty pillow shapes:** contour and ergonomic pillows may need dedicated cases even when one measurement looks close to a conventional size. ## Frequently Asked Questions ### What is the most common pillow size in Hong Kong? There is no single official size. Around 50 x 75 cm and 50 x 80 cm are common among major international bedding retailers in Hong Kong, while 43 x 63 cm and specialty sizes are also widely available. Check dimensions rather than relying on the word “standard”. ### What is Hush Home’s pillowcase size? Hush Home’s adult pillowcase size is 51 x 77 cm. This applies to the adult pillowcase dimension listed in Hush Home’s bedding size guide, and the Mulberry Silk Pillowcase™ is explicitly specified at 51 x 77 cm. ### Is a 50 x 75 cm pillow a standard size? It is a very common adult rectangular size, but “standard” is not universal. Some Hong Kong retailers use 50 x 80 cm, 43 x 63 cm or other dimensions, so the centimetres are more reliable than the category name. ### Can a pillowcase be slightly bigger than the pillow? Yes. A small amount of extra room is normal because a pillowcase is measured flat and must accommodate the pillow’s depth and fullness. The aim is a secure fit without tightly compressing the pillow or leaving excessive loose fabric. ### Can I use a 50 x 80 cm case on a 50 x 75 cm pillow? Usually yes, although there will be a little extra fabric at the long end. An envelope closure can help keep the pillow looking neater. ### Can I use a 50 x 75 cm case on a 50 x 80 cm pillow? It may be too tight, particularly with a full or firm pillow. A matching or slightly larger case is safer. ### Do I need King pillows for a King bed? No. A King mattress can use two standard-sized adult pillows perfectly well. Longer King pillows mainly change the amount of sleeping surface and the visual fullness across the headboard. ### Does a higher pillow need a bigger pillowcase? Not necessarily. If the pillow’s length and width stay the same and the case has enough fabric volume, different lofts can use the same case. Hush Home’s 50 x 75 cm Loft Pillow™, for example, comes in both 12 cm and 15 cm heights. ### What size pillowcase fits the Hush Home Miracle Pillow™? The Miracle Pillow™ measures 35 x 65 cm across its face and can be adjusted to 12, 14, 16 or 18 cm high. Hush Home’s 51 x 77 cm Mulberry Silk Pillowcase™ is explicitly listed as compatible with the Miracle Pillow™. ### What size pillowcase fits the Hush Home OnePillow™ and Loft Pillow™? Both pillows use a 50 x 75 cm face size. Hush Home’s adult 51 x 77 cm pillowcase format is a close fit, and the Mulberry Silk Pillowcase™ is specifically listed as compatible with both models. ## Final Takeaway The most important lesson is that Hong Kong does not have one universal pillow size. Common adult pillows may be 50 x 75 cm, 50 x 80 cm, 43 x 63 cm or another shape entirely. Imported labels such as Standard, Queen and King can be useful shorthand, but centimetres are the safer way to compare products. For pillowcases, aim for a secure fit with enough room for the pillow’s actual fullness. Do not confuse pillow length and width with loft, and do not assume your mattress size dictates your pillow size. Measure the pillow itself, check the closure, and follow the manufacturer’s compatibility guidance for unusually thick or shaped designs. Within Hush Home’s range, the main adult pillowcase format is 51 x 77 cm, while the pillows themselves use different face dimensions and heights according to their construction. That variety is intentional: pillowcase fit and sleep support are related, but they are not the same decision.
