Quick answer: To measure your sofa for a corner scratcher, measure from the floor to the top of the arm at the front corner, note whether the arm is square or rounded, check the floor space beside it and note which side your cat scratches. Then choose the closest table height: 21.5, 23.5 or 25.5 inches.

A corner scratcher table only works if it fits. If it is too short, your cat keeps scratching the exposed fabric above it. If it is too tall, it looks odd and can block the arm. If it sits on the wrong side, it protects a corner your cat never touches. The good news: getting the fit right takes a tape measure, five minutes and the short method below.
What you need
- A rigid or soft tape measure (a rigid one is easier for vertical measurements).
- Your phone to take a photo of the corner and note the numbers.
- About five minutes, ideally with your cat out of the room so the tape does not become a toy.
A side table for you. A scratcher for them.
The CozeCat Side Table sits flush against your sofa arm: a table top for your coffee and remote, a replaceable natural-sisal scratching surface for your cat. Choose Left, Right or Pair, Walnut or Maple, and a 0, 2 or 4-inch riser to match your arm height.
Step 1: How high is the arm at the front corner?
Stand the tape on the floor right at the front corner of the sofa arm, where your cat scratches. Measure straight up to the highest point of the arm. Write the number down to the nearest quarter inch.
Measure at the corner, not the middle of the arm. Many sofas have arms that slope or curve, and the corner is the spot the scratcher has to cover.
If your sofa has removable cushions on the arm
Measure to the top of the fixed arm frame and note the cushion height separately. A scratcher table sits next to the frame, so the frame height matters most.
If the arm is padded and squishy
Press down lightly, the way an elbow would. Record both the resting and pressed heights. Use the resting height for planning.
Step 2: Is the arm square or rounded?
Look at the corner from above and from the front:
- Square or track arm: a flat side and a sharp corner. Scratcher tables sit flush easily.
- Rolled arm: the arm curves outward at the top. The table will touch the lower part of the arm; that is fine as long as the scratching surface covers the corner your cat uses.
- Flared or sloped arm: the arm leans out. Check that the base of the table will not be pushed away from the sofa.
Take a photo from the front and one from the side. It helps if you need to ask a retailer about fit.
Step 3: How much floor space is beside the arm?
Measure from the side of the arm to the nearest obstacle: a wall, a lamp, a radiator or a doorway. A side table needs room to stand beside the arm, and you need room to walk around it. Also check the floor surface. On a thick rug the table may sit slightly higher; on a hard floor, felt pads help protect the floor.
Step 4: Which side does your cat scratch?
Look for the damage. Scratching usually shows as pulled loops, frayed fabric or scuffed leather on one corner more than the other. If you face the sofa from the front and your cat scratches the corner on your right, that is the right-hand arm as you face it. Product names for Left and Right versions can be defined differently, so check the retailer's side guide before ordering. If both corners are damaged, plan for both.
Step 5: Which table height matches your sofa?
Here is how the measured arm height compares with the three CozeCat heights. The goal is a table that reaches close to the top of the arm without towering over it.
| Your arm height (floor to top, at the corner) | Closest CozeCat height | Notes |
|---|---|---|
| About 21 to 23 inches | 21.5" (base) | Common on modern low-profile sofas |
| About 23 to 25 inches | 23.5" (with 2" riser) | Typical of many standard sofas |
| About 25 inches and up | 25.5" (with 4" riser) | Taller or traditional sofas |
| Under about 20 inches | Base height may sit above the arm | Ask support before ordering |
If you fall between two sizes, choose the one closer to your arm height. A table slightly below the arm still covers the area cats scratch most, since most scratching happens below the top edge while the cat stretches.
A side table for you. A scratcher for them.
The CozeCat Side Table sits flush against your sofa arm: a table top for your coffee and remote, a replaceable natural-sisal scratching surface for your cat. Choose Left, Right or Pair, Walnut or Maple, and a 0, 2 or 4-inch riser to match your arm height.
What are the most common measuring mistakes?
Measuring the back of the sofa instead of the arm
The back is usually several inches taller. A table sized to the back will tower over the arm.
Measuring in the middle of a sloped arm
On sloped arms the middle can be lower than the front corner. Always measure where the table will stand.
Forgetting about the rug
A thick rug can add height to the table but not to the sofa if the sofa legs sit off the rug. Measure the sofa and the table position on the same surface, or account for the difference.
Ignoring which corner the cat uses
Two well-sized tables on the wrong side do nothing. Spend a day watching where your cat heads after a nap; most cats scratch right after waking.
What to do with your numbers
Once you have your arm height, arm shape, floor space and side, you are ready to choose. On the cat scratcher side table page you can pick Left, Right or Pair, a Walnut or Maple finish and the base, 2-inch or 4-inch riser height. Each CozeCat corner scratcher table has a plywood frame with a wood finish, a top that holds up to 50 lbs and a Velcro-backed natural sisal mat that can be replaced when it wears out.

A quick checklist before you order
- Arm height at the front corner, to the nearest quarter inch.
- Arm shape: square, rolled or sloped.
- Floor space beside the arm, plus floor surface.
- Which corner your cat scratches, or both.
- Finish that suits the room: Walnut for warmer, darker rooms; Maple for lighter ones.
Getting your cat to use it
Fit is half the job. The other half is placement and encouragement. Put the table flush against the exact corner your cat scratches, rub a little catnip or silvervine on the sisal, and reward your cat with a treat the first few times they use it.

Bottom line
Measure the arm height at the corner, note the arm shape and floor space, confirm which side your cat scratches, then pick the table height closest to your arm. That is the whole method. A well-fitted corner scratcher looks like it belongs to the sofa, and that is what makes it work for both you and your cat. The CozeCat Side Table comes in 3 heights (21.5, 23.5 and 25.5 inches) and as a Left, Right or Pair, so these measurements translate straight into the right table.
FAQ: how to measure sofa for corner scratcher
Where exactly should I measure my sofa arm height?
At the front corner of the arm, from the floor straight up to the highest point of the arm frame. That is the spot your cat scratches and where the table will stand.
Should the scratcher table be taller or shorter than the arm?
Close to the arm height is ideal. Slightly shorter is usually fine because cats scratch below the top edge while stretching. Much taller looks odd and can block the arm.
What if my sofa arm is about 24 inches?
That sits between the 23.5-inch and 25.5-inch CozeCat heights. Choose the one closer to your measurement, which here is usually 23.5 inches with the 2-inch riser.
Does a rolled arm work with a corner scratcher table?
Usually yes. The table stands against the lower part of the arm and the sisal covers the corner. Check that the base can sit flush and is not pushed outward.
How do I know if I need a pair?
If both front corners show scratching, or you have more than one cat with different favorite sides, a pair covers both arms at once.
A side table for you. A scratcher for them.
The CozeCat Side Table sits flush against your sofa arm: a table top for your coffee and remote, a replaceable natural-sisal scratching surface for your cat. Choose Left, Right or Pair, Walnut or Maple, and a 0, 2 or 4-inch riser to match your arm height.
