To measure a bar stool cover accurately, measure the seat’s diameter from the bottom and the side band thickness with a firm carpenter’s tape — your measurements will depend on whether you have a simple round stool or a fully upholstered bar chair.
A cover that’s just an inch off looks sloppy and slides around. The right measurement, on the other hand, means a clean fit that stays put. The method changes depending on your stool’s shape, so start by identifying which type you have. Below are the two main measurement paths — round stool seats and full bar chairs — plus the common mistakes that trip people up.
Measuring a Round Stool Seat Cover
Round stools need two measurements: the seat diameter and the side band thickness. Flip the stool over so you’re measuring from the bottom of the seat — the widest point is the diameter. Measure the side band (the vertical lip around the cushion) at its thickest point. Vendors typically list this as “height” on the product page.
Measuring a Full Bar Chair Cover
For upholstered bar chairs with backs and arms, take three measurements at the widest and deepest points. Measure width from left to right at the widest spot — start at the leg base or the arms if they extend further. Measure depth from the back of the chair to the front, starting at the top or bottom of the chair back if the design curves. Measure overall height from the floor to the highest point of the chair. It’s always better to go up a size than to force a cover that’s too tight — a snug cover fights you during installation, strains seams, and traps moisture.
If you have a shaped or unusual chair, measure at the widest point in every direction, not at a narrow middle section. Many a perfect-looking cover has been returned because someone measured the waist instead of the hips.
Fit Guidance from Retail Listings
Actual product listings show the range you’re aiming for. If your stool sits at a counter rather than a full bar, note the height conventions:
Three Mistakes That Ruin the Fit
The most common measurement errors are easy to avoid once you know them.
- Using a flexible tape. A soft tailor’s tape bends and curves around the seat, making the diameter read smaller than it really is. A firm carpenter’s tape stays straight and gives you the true number.
- Measuring only the seat top. On round stools, the top is often narrower than the base. Measure from underneath, at the bottom of the seat, so you capture the widest point.
- Choosing too tight a fit. A cover that’s slightly oversized settles better, breathes, and stays in place. One that’s too tight strains at the seams and won’t drape properly.

FAQs
Can I use a tailor’s tape to measure a stool seat?
You can, but the result will be less accurate. A flexible tailor’s tape can sag around the seat’s curve and understate the diameter. A firm carpenter’s tape is recommended for a precise measurement that matches how cover manufacturers size their products.
Do I need to measure the stool’s height for a seat cover?
Only if you’re buying a full bar chair cover that wraps around the back and sides. For a simple round cushion cover, the two measurements you need are the seat diameter and the side band thickness — height from the floor is not relevant.
Is it better to size up or size down?
Size up. A cover that is slightly wider and deeper than your measurements will fit more smoothly, stay in place better, and allow airflow. A cover that is too tight strains the fabric, resists installation, and can trap moisture against the cushion.
