Determining the size of your mattress is a straightforward process that involves measuring its length, width, and height (or thickness). To quickly identify the size, grab a measuring tape, and measure from the head of the mattress to the foot for length, and from one side to the other for width. Once you have these measurements, you can compare them to standard mattress sizes, which are typically labeled as Twin, Twin XL, Full (or Double), Queen, King, and California King. If you have the mattress manufacturer’s details to hand, you can also check any tags or labels that may indicate the size.
Understanding Mattress Dimensions
Before you grab your measuring tape, it’s useful to familiarize yourself with the common mattress sizes available on the market. This knowledge will help you understand which category your mattress most likely fits into.
Twin Size
The twin mattress is one of the smallest standard sizes available. Typically, a twin mattress measures 38 inches in width by 75 inches in length. They are an ideal choice for children’s rooms or small bedrooms and are often used in bunk beds.
Twin XL Size
A Twin XL mattress is similar to the standard twin but is longer. It measures 38 inches in width by 80 inches in length, making it more suitable for taller individuals or for use in college dorm rooms.
Full (Double) Size
Full mattresses, sometimes referred to as double mattresses, measure 54 inches in width by 75 inches in length. These are wider than twin mattresses and can comfortably sleep one person or accommodate two adults in a snug fit, making them a good option for guest bedrooms.
Queen Size
Queen-size mattresses offer more space and are the most popular option for couples. The typical queen mattress dimensions are 60 inches in width by 80 inches in length.
King Size
King-size mattresses are significantly wider than queen-size mattresses, measuring 76 inches in width by 80 inches in length. They offer ample space for two people to sleep comfortably and are often a top choice for master bedrooms.
California King Size
The California King mattress is designed for those who need extra length and is perfect for taller individuals. It measures 72 inches in width by 84 inches in length, giving it an extra 4 inches in length compared to a standard king mattress.
Measuring Your Mattress
Once you are acquainted with standard mattress sizes, measuring your mattress is the next step. For the most accurate measurements, remove all bedding from your mattress, including sheets and mattress protectors.
Tools You’ll Need
To measure your mattress, you need a reliable measuring tape that can measure at least 84 inches (or 7 feet). A notepad and pen may also be helpful for recording the measurements.
Steps for Measuring
Follow these steps to measure your mattress:
1. Begin by measuring the width. Place the end of the tape measure at the left edge of the mattress and extend it to the right edge. Ensure the measuring tape is straight and covers the widest part of the mattress. Record this measurement.
2. Next, measure the length. Position the end of the measuring tape at the top (head) of the mattress and pull it straight down to the bottom (foot). Again, make sure the measuring tape is straight. Record this length.
3. If you also need to know the height (or thickness) of your mattress, measure from the top surface where you would sleep directly down to the bottom edge (the side of the mattress). This measurement can be useful if you’re buying fitted sheets or a mattress protector. Record the height.
4. Compare your measurements to the standard sizes mentioned earlier to determine your mattress size.

10% OffConsiderations When Measuring
When measuring your mattress, keep in mind that mattresses can sometimes have slight variations in size due to manufacturing processes, wear and tear, or the addition of mattress toppers. If your mattress measurements are off by an inch or so, it is generally still safe to consider it within a standard size category.
Finding the Mattress Tag
Many mattresses will have a tag stitched onto them that indicates the size, brand, and other information. This can be found at the head or the foot of the mattress or along one of the sides. Check for this tag as it can quickly tell you your mattress size without requiring measurements.
Using a Mattress Size Chart
Mattress size charts are handy tools that list standard mattress dimensions. You can find these charts online and in many brick-and-mortar mattress stores. Once you have your mattress measurements, you can match them to a size on the chart to confirm its size category.
Special Considerations
Some mattresses may not conform to standard sizes, such as custom-made or antique beds. In these cases, you may need custom bedding, or you may have to modify standard-size bedding to fit. Similarly, mattresses designed for RVs, boats, or other non-standard spaces may have unique dimensions.
Finishing Thoughts
Knowing the size of your mattress is essential when you’re buying new bedding, planning to move, or simply trying to optimize your sleep space. By measuring your mattress or checking its tag, you can match its dimensions to the standard mattress sizes and find the right fit for sheets and bed frames. Always remember to measure accurately, and if your mattress is non-standard, don’t forget to consider custom options for a perfect fit. With this guide, you should feel confident in determining the size of your mattress and making informed decisions to enhance your sleep experience.
