BEDROOM REFERENCE
Standard Mattress Sizes.
Understanding your mattress dimensions is the first step toward selecting appropriately sized sheets, mattress protectors, and bedding layers. Use this U.S. reference chart as a starting point.
U.S. Mattress Dimensions
Width × Length
| Bed Size | Width | Length |
|---|---|---|
| Twin | 38 in | 75 in |
| Twin XL | 38 in | 80 in |
| Full | 54 in | 75 in |
| Queen | 60 in | 80 in |
| King | 76 in | 80 in |
| California King | 72 in | 84 in |
These are general U.S. mattress-size references, not guaranteed dimensions for Somelle products. Actual mattress dimensions and bedding measurements can vary. Always check the individual product listing and measure your own mattress before ordering.
THE MEASUREMENT METHOD
Three Simple Measurements.
A flexible measuring tape and a few moments of preparation can help you choose with greater confidence.
Measure End to End
Measure the full mattress length from the head to the foot. Compare your measurement with the standard size reference.
Include Every Layer
Measure from the bottom of the mattress to the top of the sleep surface, including any mattress topper or pad. Compare this with the fitted sheet's pocket-depth specifications.

BEYOND THE MATTRESS
The Perfect Pillow Fit.
Pillow dimensions influence both comfort and the finished appearance of your bed. Choosing the right pillowcase or sham begins with understanding the size of the pillow insert.
Standard pillow sizes can provide a useful starting point, but actual product dimensions may differ. Always compare the measurements listed for your pillow and its cover.

GUIDANCE BY PRODUCT
Fit for Every Room.
The right measurements depend on the item you're choosing. From fitted sheets to window textiles, each product category has its own important details.
Select a category to explore what you should measure before placing your order.
Sheet Sets & Bedding Protectors
Measure your mattress width, length, and total depth. Fitted sheets and mattress protectors should be selected using the product's specific size and pocket-depth information.
If you use a topper or mattress pad, include its thickness when comparing measurements. A mattress labeled Queen, for example, may still vary in overall height from another Queen mattress.
Duvet Covers, Comforters & Quilts
Check the actual width and length of the duvet insert or bedding layer. Duvet covers should be selected according to the insert's dimensions, not solely the mattress size label.
For comforters and quilts, consider how much fabric you would like to extend over the sides and foot of your bed. Bed height and your styling preference can affect the finished appearance.
Pillows, Pillowcases & Shams
Measure the pillow insert's width and length, then compare them with the stated cover dimensions. Decorative pillow shams may have different closures or finishing details from everyday pillowcases.
For specialty and support pillows, review the height, shape, and product-specific measurements, especially when choosing a compatible protective cover.
Mattress Toppers & Pads
Match the topper or pad's stated width and length with the dimensions of your mattress.
For a topper, consider its thickness and how it changes the overall mattress height. This can affect the fitted sheets and protectors you use.
Bath Towels, Mats & Bathrobes
For bath towels, compare the stated dimensions with your preferred coverage and use. For bath mats, measure the available floor area and consider door clearance.
When choosing a bathrobe, consult the individual garment measurements. Pay particular attention to chest or body width, length, and the intended fit.
Curtains & Window Textiles
Measure the curtain rod or track width, then determine your desired panel fullness.
For the length, measure from the intended hanging point to your chosen finish, such as above the sill, below the sill, or close to the floor.
Consider the heading style, number of panels, and the product's actual measurements before selecting a size.
Cushions, Throws & Table Linens
For cushions, compare the cover dimensions with the cushion insert. For throws, consider whether the textile will be draped over a sofa, layered across a bed, or used for personal comfort.
For table linens, measure the tabletop width and length, then decide how much overhang you would like around its edges.
THE DETAILS OF A ROOM
Measure with Intention.
Window textiles are an important part of a room's overall proportion. Their length, width, and gentle folds can change the way natural light moves through the space.
Before choosing curtains, consider the window itself, the hanging hardware, and the finished look you prefer.
01
Measure the Rod or Track
Record the full hanging width, not simply the glass opening.
02
Choose Your Curtain Length
Decide where you want the curtain to finish, then measure from its intended hanging point.
03
Consider Fabric Fullness
A fuller appearance may require more total panel width than the rod width alone.
04
Check Each Panel Specification
Confirm the number of panels, their individual dimensions, and the heading style.

HELPFUL ANSWERS
Sizing Questions.
From bedding dimensions to curtain measurements, explore answers to some of the most common sizing considerations.
Are all bedding sizes the same across brands?
No. While standard size labels provide a useful reference, actual bedding dimensions can vary between manufacturers and individual products.
Always compare the published product measurements with your mattress or existing bedding insert.
How do I know if a fitted sheet is deep enough?
Measure the total height of your mattress, including any topper or pad. Compare this with the fitted sheet's stated pocket depth and fit guidance.
Do not rely only on the terms "deep pocket" or "extra deep pocket" without checking the specifications.
Should my duvet cover match my mattress size?
Your duvet cover should primarily be selected according to the dimensions of your duvet insert.
Mattress size can help you decide how much drape you prefer, but the insert and cover measurements are particularly important for compatibility.
What should I measure before buying pillowcases?
Measure the length and width of your pillow insert, then compare those measurements with the selected pillowcase.
For decorative shams, also consider the intended finished appearance and the closure design.
How can I select the right curtain length?
Start at the intended hanging position and measure to your preferred curtain finish.
The heading style and placement of your curtain rod or track can affect the final length.
Can I use this guide for every Somelle product?
This guide provides general sizing assistance across Somelle's home textile categories.
Individual products may have different dimensions, construction details, or fit requirements. The product listing should always be your final measurement reference.
What if I order an item in the wrong size?
