To wash decorative pillow covers without shrinking them, use cold water on a gentle or delicate cycle and always air dry instead of using high heat. Heat is the main cause of shrinkage, so keeping everything cool and low agitation protects cotton, linen and blended fabrics.
Below you will find a simple, fabric-safe method that works for most removable covers, plus tips for drying, reshaping and preventing future shrinkage. If you are updating your living room look, explore our guide to the best throw pillows for sofas and cozy corners for style ideas that pair with proper care.
How to Wash Decorative Pillow Covers and Keep Their Size
1. Check the Label and Fabric Type First
Your care label tells you if the cover is machine washable or should be handled more gently, and it often lists the exact fiber content. Cotton and linen are most prone to shrinking because their natural fibers swell and contract with heat, while polyester blends, microfiber and acrylic resist shrinkage much better.
If the label says dry clean only, spot clean only or shows embellishments like embroidery, beads, tassels or leather trim, skip the machine entirely. For those covers, hand washing in cool water or taking them to a professional cleaner is the safest route to keep their shape and detail intact.
2. Prepare Covers Before Washing
Close all zippers and turn covers inside out to reduce friction and protect prints, textures and stitching from rubbing against the drum. Shake them outside to remove dust and give them a light vacuum if you have pets, as grit can abrade delicate weaves during the cycle.
Wash similar colors and fabrics together and never overload the washer, since crowding prevents proper rinsing and can stretch seams unevenly. Giving covers room to move helps them clean evenly, and you can place delicate or embellished covers in a mesh laundry bag for an extra layer of protection.
3. Use Cold Water and a Gentle Cycle
Select cold water and the delicate or gentle cycle with a low spin speed to minimize agitation. Cold water prevents the fiber contraction that causes shrinkage, and a gentle cycle keeps seams, piping and decorative weaves from pulling or puckering.
Use a small amount of mild liquid detergent made for delicates and skip fabric softener, bleach and hot water, which can weaken fibers and set shrinkage. If you are washing by hand, fill a basin with cool water, add detergent, soak for 5 to 10 minutes, swish gently, then rinse thoroughly in cool water until it runs completely clear.
4. Air Dry the Right Way to Avoid Shrinkage
Never put decorative covers in a hot dryer, even for a few minutes to finish drying, because high heat locks in shrinkage quickly. Instead, press gently with a clean, dry towel to absorb moisture without wringing or twisting, which can distort the shape and crease the fabric.
Lay flat on a drying rack or hang to air dry away from direct sunlight and direct heat sources that can fade colors or tighten fibers. While the cover is still damp, smooth it with your hands, pull corners square and align seams so it dries to its original dimensions. For more cozy textile care tips, see our best throw blanket guide for cozy style and comfort.
5. Reshape, Steam and Put Back on Properly
When the cover is almost dry but still slightly damp, fitting it back over the pillow insert lets it finish drying in its true shape. This technique helps cotton and linen relax without shrinking and naturally reduces wrinkles, so you get a smooth, tailored look without extra heat.
If wrinkles remain, use a garment steamer on low or iron on the lowest setting suitable for the fabric, always inside out and with a pressing cloth for protection. Store extra covers flat and consider using a protective inner encasement to keep inserts clean longer, so you wash the outer covers less often.

The Aogigigio Pillow Core Laundry Bag 2-Pack is an X-Large mesh washing solution sized at 50 x 70 cm to hold standard pillow cores, bulky bedding inserts and large plush toys. It is built for households, pet owners and anyone who regularly machine washes bulky items that need extra protection from agitation and spinning.
In real world use, the large mesh allows water and detergent to circulate freely for a thorough clean while keeping pillows contained and protected. The zipper stays secure throughout the cycle and the integrated hanging straps make the transition from washer to clothesline or drying rack seamless, helping pillows dry evenly without flattening.
Constructed from durable polyester, the bags feel sturdy yet breathable with reinforced straps and a smooth running zipper closure. The mesh is strong enough to resist snagging and tearing during rough cycles, while the square shape provides ample room so fillings are not bunched or compressed unnecessarily.
The generous size still has limits, so very thick or oversized pillows should be measured before purchase to ensure a proper fit. As noted by users, pulling the compression straps too tight can restrict water flow to the center of the pillow, so finding a balanced tension is important for the best wash results.
Overall, this is a practical and well designed laundry accessory that solves a common problem of washing bulky pillows and toys safely. For the convenience, protection and thoughtful drying features offered in a handy two pack, it is a smart addition to any laundry routine focused on extending the life of bedding and plush items.

The Kingnex Waterproof Pillow Protectors are 18x18 zippered covers built specifically for feather and down throw pillows. They are perfect for anyone tired of feathers poking through fabric, constant shedding, or couch cushions that sag and lose volume.
In real world use they excel at containing feathers while adding reliable waterproof protection against perspiration, drool and everyday spills. Users report cushions look fuller, hold shape longer and stay mess free, all without the loud crinkling often associated with waterproof covers.
Design and build quality focus on comfort and practicality. The exterior uses soft, breathable bamboo viscose terry that feels pleasant to the touch, while the interior features a flexible, quiet waterproof membrane. A fine tooth zipper provides complete 360 degree protection and the terry texture helps anchor the protector inside decorative shams.
There are a few drawbacks to note. The terry surface can feel a bit stiff at first and has an unusual texture until it softens with washing. The waterproof lining also adds firmness, which can make some pillows feel less lofty, and the snug sizing means plush inserts need a firm squeeze to fit.
Overall, these protectors offer a smart, low maintenance solution for extending the life of feather pillows. If you want to eliminate feather poke through, guard against stains and keep throw pillows supportive and full, this two pack is a practical and effective choice.
Mesh laundry bags cushion delicate covers during the wash and prevent snags, a gentle detergent like Woolite protects fibers and colors in cold water, and waterproof pillow protectors keep your inserts fresh so you can wash the decorative outer covers less frequently.
When This Won’t Fix It
If your cover has already shrunk significantly in a hot wash or hot dryer, cold washing will not stretch it back to its original size, and dry clean only fabrics like silk, velvet or wool blends can be damaged by any machine washing. In those cases, take the cover to a professional cleaner for assessment or replace it, and use a tailor for minor alterations if the fit is just slightly tight.
Frequently Asked Questions
Can you put decorative pillow covers in the dryer without shrinking them?
You can, but only on air dry or no heat tumble for a short time to fluff, and it is safer to air dry completely. High heat is what shrinks cotton and linen, so if you must use the dryer, choose the lowest heat or delicate setting and remove the cover while still slightly damp to reshape. In 2026, most modern dryers have a delicate or air only option that works well for this purpose.
Why did my pillow covers shrink after washing?
Shrinkage usually happens from hot water, high dryer heat or aggressive agitation that tightens natural fibers and seams. Cotton and linen are especially sensitive, while prewashed or synthetic blends shrink much less. To prevent it next time, always wash cold, use a gentle cycle, avoid high heat drying and reshape the cover while it is still damp.
How often should you wash decorative pillow covers?
For living room pillows, every 3 to 6 months is enough unless there are spills, pets or allergy concerns that require more frequent cleaning. Using a washable inner protector lets you extend time between washes and keeps the decorative cover fresher longer.
