How to Measure your Mattress for a Fitted Sheet

While it may seem like all Fitted Sheets are the same, choosing the right size for your mattress can be a tricky task. Here at I Love Linen, we offer 3 different depths of our French Linen Fitted Sheets, 30cm, 40cm & 50cm to ensure you get the correct fit no matter what type of mattress you have.

Having the correct size Fitted Sheet for your bedroom not only looks better on your bed, but also means it is more likely to stay put during the night.

Simply looking at your mattress to determine the depth may not be accurate enough to know the most suitable size for your fitted sheet. We recommend using a measuring tape or even a ruler to get a more accurate measurement.

If you sometimes use a Mattress Topper on your bed, this also needs to be considered when collecting measurements.


Watch the tutorial below

Place your hand flat along the top of the mattress. In this hand, hold a measuring tape or ruler and measure from the highest point to the lowest point of your mattres. We recommend allowing at least 4cm of extra depth on the fitted sheet to tuck under the mattress. For example, if your mattress measures 36cm, we recommend choosing a 40cm Fitted Sheet or if your mattress measures 31, we still recommend choosing a 40cm depth.

If you use a mattress topper, make sure to include this in your mattress measurement as it can make a difference! The mattress topper in this reel added an extra 10cm to the total depth.

A lot of love and time goes into making your linens, and for the most part, all items are made by people and not machines. While we state the intended sizes and measurements, there may be a variation of up to 6%, reflecting that each piece is unique and made by hand. This is why we recommend rounding up your sheet depth and tucking any excess underneath your mattress.

30CM

Typically, if you have a firmer mattress that does not have a pillowtop a 30cm Fitted Sheet is the most likely to fit correctly. For example a Koala or Ecosa branded mattress typically suit a 30cm Fitted Sheet.

40CM

The average sized mattress with a standard pillowtop is suited for a 40cm Fitted Sheet.

50CM

If you have an ultra plush mattress or use a large Pillow Topper, a 50cm Fitted Sheet is the most suitable.

At I Love Linen, our fitted sheets are 100% Pure French Flax Linen. Just like your favourite pair of jeans, your Linen relaxes with the warmth and movement of your body and once washed will return to its original fit. However, as Linen is a softer fibre with a looser weave, the fabric can have some stretch overtime. With regular use and washes the softness of the Linen fibre may cause your Fitted Sheet to relax in its fit over time.

Please note, our Linen is a delicate, natural fibre that requires specific care. To increase the longevity of your French Linen Sheets, especially your Fitted Sheet we recommend rotating your sheets weekly with two other Sheet Sets to avoid the wear that comes with regular contact.
