Quick answer: Before building a scratcher table, measure five things at the sofa corner: arm height, arm depth, the gap between arm and wall, the walkway beside it, and how high your cat scratches. In our example, a 62 cm arm and a 48 cm scratch height lead to a 60 cm table with sisal up to 55 cm.
A scratcher table has to do two jobs at once: it must sit neatly beside the sofa as furniture, and it must sit exactly where the cat scratches. Getting the size wrong by a few centimetres can leave a gap the cat still uses, or a table that blocks the walkway.
This article works through one real-world style example with numbers. For the general measuring routine, see our guide to measuring your sofa for a corner scratcher.
The Five Measurements
- Arm height: floor to the top of the sofa arm.
- Arm depth: front to back of the arm, where the table will sit alongside.
- Gap to the wall or next piece of furniture at the side of the arm.
- Walkway width in front of that gap.
- Scratch height: the highest fresh claw mark on the arm, measured from the floor.
Write each one down in centimetres. Measure twice, and measure the scratch height on a day when the marks are fresh.
Our Example Sofa
| Measurement | Example value |
|---|---|
| Arm height | 62 cm |
| Arm depth | 90 cm |
| Gap to wall | 52 cm |
| Walkway in front | 85 cm |
| Highest scratch mark | 48 cm |
This is a typical three-seat fabric sofa with a cat that scratches the front and outer side of the arm.
Working Out the Table Height
A side table usually looks right when its top sits level with the arm or up to about 5 cm below it. With a 62 cm arm, a table height of 57 to 62 cm fits. We chose 60 cm, which leaves the top 2 cm below the arm, so a drink on the table sits within easy reach.
Our guide to matching scratcher table height to the sofa arm explains why a slightly lower top tends to look better.
Setting the Sisal Height
The scratching face has to reach above the highest claw marks, with some margin for a full stretch. The marks in our example reach 48 cm, so sisal up to 55 cm gives 7 cm of headroom while leaving a timber band of about 3 cm under the 60 cm top. That band stops the top edge fraying.
Choosing the Top Size
The table must fit the 52 cm gap to the wall with room to slide it in and out. A 45 x 45 cm top leaves 7 cm of space, which is enough to clean behind without the table looking lost. A deeper top would block the gap completely, and cats sometimes squeeze behind a table that fits too tightly.
Checking the Walkway
With 85 cm in front of the gap and a table that stands flush with the arm front, the walkway stays at 85 cm. Most people find 75 to 90 cm comfortable for a main route. If the table had stuck out 10 cm past the arm, the walkway would drop to 75 cm, which is tight in a busy room.
Turning Numbers Into a Cut List
| Part | Size | Notes |
|---|---|---|
| Top | 45 x 45 cm, 18 mm plywood | Rounded corners |
| Base | 45 x 45 cm, 18 mm plywood | Felt pads underneath |
| Scratching side | 45 x 56.4 cm, 18 mm plywood | Sisal wrapped to 55 cm from floor |
| Back side | 45 x 56.4 cm, 18 mm plywood | Faces the wall |
The two side panels fit between top and base: 60 cm minus two 18 mm boards leaves 56.4 cm. The sisal starts above the base, so on the panel it covers about 53 cm, ending roughly 3 cm below the underside of the top.
Common Measuring Mistakes
Measuring arm height at the cushion rather than the frame top. Forgetting that skirting boards stop a table sitting flat against the wall. Measuring scratch height on a lazy day, when the cat only rakes low. Ignoring a radiator or socket that sits in the gap. Each of these can push a build out by several centimetres.
Which Side of the Table Faces the Cat
Turn the sisal side toward the spot the cat scratches. If the cat scratches the outer face of the arm, the sisal faces outward, into the room. If it scratches the front, consider wrapping two sides. Our article on sofa corner placement explains why position matters more than adding another post.
Building or Buying After You Measure
Once you have the numbers, you can build to them or compare them with a ready-made table. A DIY build like this takes a weekend and a set of basic tools. Our DIY versus buying guide goes through cost and time in detail.
If you would prefer not to build, check the dimensions of the CozeCats Side Table against your five measurements. It is designed to stand beside a sofa arm, with sisal on the scratching side and a usable top.
Measured and ready If your numbers match, the CozeCats Side Table can go straight into the gap you measured. It ships with next-day shipping, and if the fit is wrong you can return it within 30 days, paying the return shipping.
Measuring a Sectional or L-Shaped Corner
On a sectional, the corner where two sections meet is rarely the problem; cats usually go for the open ends. Measure each open end as a separate corner, using the same five steps. If one end sits against a wall and the other faces the room, the room-facing end usually needs the table first, since it is the one the cat passes on its way through.
Chaise ends are lower than standard arms on many sectionals, sometimes by 10 cm or more, so a table sized for the main arm may look too tall there.
Checking Floor Level and Skirting
Lay a spirit level on the floor across the gap. Older floors can slope by a centimetre or more over half a metre, which makes a table rock. Felt pads of different thicknesses fix small slopes. Measure the skirting board depth too; a 2 cm skirting means the table cannot sit flush against the wall, so if you measured the gap above the skirting, subtract its depth to get the space at floor level.
Re-Measuring After a Sofa Change
New cushions, a different sofa or a move to a new room all change the numbers. Repeat the five measurements before moving the table, and adjust felt pads or the sisal wrap if the arm height shifts by more than 3 cm.
Our guide to protecting a new couch from cats covers the first weeks with a new sofa.
Recording the Plan
Keep your measurements and cut list in a phone note with a photo of the corner. If the sisal wears out, you will know exactly how much rope to buy, and if you build a second table for the other arm, the numbers are ready. Our guide to tables for both sofa arms covers that next step.
Why Behaviour Comes First
A perfectly sized table only works if the cat uses it. Cats scratch to mark territory and stretch, often right after waking. International Cat Care on scratching furniture and Humane World for Animals on destructive scratching both stress putting the scratcher where the cat already scratches.
Sofa Corner Measuring Questions
What should I measure before building a scratcher table?
Five things: arm height, arm depth, the gap between the arm and the wall, the walkway in front, and the highest fresh claw mark on the arm. Measure each twice in centimetres and write them down before you draw a cut list.
How tall should a scratcher table be next to a sofa?
Level with the arm or up to about 5 cm below it usually looks right. With a 62 cm arm, a table of 57 to 62 cm fits; in our example we chose 60 cm, leaving the top 2 cm below the arm.
How high should the sisal go on a scratcher table?
Above the highest claw marks, with a few centimetres of margin for a full stretch. In our example the marks reached 48 cm, so sisal up to 55 cm gives 7 cm of headroom and leaves a timber band of about 3 cm under the top.
How much space should I leave beside the table?
Leave a few centimetres so the table slides in and out for cleaning. A 45 cm top in a 52 cm gap leaves 7 cm. Avoid a tight fit, as cats sometimes squeeze behind a table that is wedged into the gap.
What are the most common sofa measuring mistakes?
Measuring arm height at the cushion rather than the frame top, forgetting skirting boards, measuring scratch height on a day the cat only rakes low, and missing a radiator or socket in the gap. Each can throw a build out by several centimetres.
