Selecting the Right Size Pillow Insert

It can be really tricky to determine what size pillow insert you need for your 18×18 pillow cover. You want it to be full and plump, but you don’t want it to be too big or too small. Here are a few things to keep in mind when selecting the right size pillow insert for your cover.

Consider the type of fabric the pillow cover is made of

When you’re searching for the perfect pillow insert, the fabric of your pillow cover is an important consideration. A natural fiber like cotton or linen will breathe better than a synthetic, so if you’re prone to night sweats, you might want to avoid polyester and opt for a more breathable fabric. If you have sensitivities to down or feathers, there are several hypoallergenic options available as well.

The density of the filling is also something to take into account — a firmer pillow will provide more support for your head and neck, while a softer one will be more comfortable for side sleepers. There are even special pillow inserts available for those who suffer from allergies or asthma.

Once you’ve decided on the type of fabric and filling you want, it’s time to select the right size pillow insert for your cover. The most important thing to remember is that the insert should be two inches larger than the cover on all sides so that it can fill out the corners and plump up the pillows. For example, if you have an 18×18 pillow cover, you will need a 20×20 pillow insert.

Consider the thickness of the pillow cover

The thickness of the pillow cover will also play a role in how full and plump your finished product looks. A lot of people mistakenly think that they need to get an insert that is the exact same size as their pillow cover, but this is not the case. In fact, you actually want your insert to be about 1”-2” larger than your pillow cover. This will allow your pillow to have a full and plump appearance, without being too overstuffed.

Consider the type of filling you want

When it comes to pillow inserts, you have a lot of options these days. Not only do you have to choose the right size for your pillow cover, but you also have to decide which type of filling you want. The most common types of pillow inserts are down, polyester and memory foam. Down pillows are considered the best quality, but they can be more expensive than polyester or memory foam. Polyester pillows are a good middle-of-the -road option – they’re not as expensive as down pillows, but they’re also not as cheap as memory foam. Memory foam is the most affordable option, but it doesn’t have the same high quality as down or polyester.

Once you’ve decided on the type of filling you want, then you can start thinking about size. If you’re using a pillow cover that’s 18×18, then you’ll need an insert that’s slightly larger in order to fill out the cover and give it a nice, full look. A good rule of thumb is to choose an insert that’s two inches larger than the cover on all sides. So, for an 18×18 cover, you would need an insert that’s 20×20.

If you’re unsure about what size insert to get, it’s always better to err on the side of too big rather than too small. You can always take out some of the filling if it’s too puffy, but if it’s too small, then your cover will look empty and won’t be very comfortable to use.
