Buying a decorative pillow sham is only half the job — the other half is choosing a pillow for sham use that actually fills it out. Slide a standard bed pillow into a sham and you’ll usually get a sad, deflated look with fabric bunching at the corners. In 2026, most bedding brands sell dedicated inserts sized specifically for sham dimensions, and picking the right one makes the difference between a crisp, styled bed and one that looks like laundry day. This guide walks through sizing, fill types, and our top picks so your shams look full from every angle.

Why a Regular Bed Pillow Doesn’t Work in a Sham
Sleeping pillows are designed for head and neck support, not visual fullness. They’re often flatter, softer in the corners, and sized to standard bedding dimensions (20×26 for standard, 20×36 for king) rather than the slightly larger dimensions many shams use. A true pillow insert for sham use is typically cut an inch or two bigger than the sham cover itself, so once it’s stuffed inside, the extra material creates that plump, no-gap look designers go for. This is the same principle behind why throw pillow covers always look better with an insert one size up.
Matching Insert Size to Sham Size
Sham sizes are not identical to pillowcase sizes, and mismatching them is the most common mistake. Use this table as a general reference, then check the specific sham’s tag since brands vary slightly.
| Sham Size | Typical Sham Dimensions | Recommended Insert Size |
|---|---|---|
| Standard | 20" x 26" | 20" x 26" to 21" x 27" |
| Queen | 20" x 30" | 20" x 30" to 21" x 31" |
| King | 20" x 36" | 20" x 36" to 21" x 37" |
| Euro | 26" x 26" | 26" x 26" to 28" x 28" |
Fill Types: Poly, Down Alternative, or Feather
Polyester Fill
Polyester-filled inserts are the most budget-friendly and hold a firmer, more structured shape, which works well behind a stack of accent shams that need to look uniform on a made bed. They’re also the most washer-friendly option if the insert ever needs cleaning after a spill.
Down Alternative
Down alternative inserts strike a middle ground — soft enough to drape a bit at the edges but structured enough to avoid sagging in the middle. This is a solid pick for anyone who wants a plush look without worrying about feathers or allergies.
Feather and Down Blend
True feather-down blends give the most luxurious, hotel-style drape, molding to the sham’s shape rather than sitting rigidly inside it. They cost more and need occasional fluffing, but for a decorative bed that’s meant to be photographed or admired, this fill delivers the most polished result.
Firmness and Overstuffing
Most decorative pillow inserts are intentionally overstuffed compared to sleeping pillows — this is by design, not a defect. A slightly-too-firm insert on day one will soften with a few weeks of use and fluffing. If an insert still feels floppy inside its sham after a month, size up rather than trying to compensate with a firmer fill.
Care and Longevity
Removable, washable inserts last longer and stay fresher, especially in households with pets or kids who treat decorative pillows as extra seating. Check the care tag before buying — some down-feather inserts recommend spot cleaning only, while most poly and down-alternative inserts tolerate a gentle machine wash and low-heat tumble dry.

Compare top-rated pillow inserts for shams and find the perfect fit for your bedding size.
Check price on AmazonWhat size pillow insert do I need for a standard sham?
Most standard shams measure 20×26 inches, so an insert sized 20×26 to 21×27 inches will fill it out fully without gapping at the corners.
Can I use a regular sleeping pillow inside a sham?
You can, but sleeping pillows are usually flatter and sized to pillowcase dimensions rather than sham dimensions, so they tend to look deflated or leave loose fabric at the edges.
Should the insert be bigger than the sham?
Yes, most decorative inserts are made 1 to 2 inches larger than the sham’s stated size specifically so the fabric stretches taut for a fuller look.
What fill type looks best in a decorative sham?
Feather-down blends give the most natural, molded drape, while polyester and down alternative fills offer a firmer, more structured look that some people prefer for a tailored bed.
Do pillow inserts need to be fluffed regularly?
Yes, especially feather and down-alternative inserts, which compress with use and benefit from a shake or fluff every time you make the bed.
Are pillow inserts machine washable?
Many polyester and down-alternative inserts are machine washable on a gentle cycle, but always check the care label since some feather-down blends recommend spot cleaning only.
How many pillow inserts do I need per bed?
A typical arrangement uses two standard or king sleeping pillows plus two to three decorative shams with matching inserts, though this varies by bed size and personal styling preference.
Can I reuse an old pillow as a sham insert?
You can if it’s the right size and still holds its shape, but older pillows often lack the loft needed to fill a sham properly, so a new insert usually gives better results.
