Why measuring beats guessing
Buying a dog gate without a tape measure is how people end up with a gate that rattles, gaps at the baseboard, or sits too low for a jumper. This guide walks through a simple measuring routine for doorways, hallways, and stairs so you can order with confidence — whether you are looking at a no-drill Gate Plus or a tall fold-away / retractable-style gate.
Measure the opening before you match a size chart
For broader choosing context, the American Kennel Club’s overview on selecting dog gates is a solid external primer: https://www.akc.org/expert-advice/home-living/dog-gates/
Tools you need (five minutes)
- Tape measure (metal preferred).
- Notepad or phone notes.
- Painter’s tape to mark bracket height.
- Optional: a level if your walls look uneven.
Step 1 — Decide the job of the gate
Write down the primary use:
- Front door / entry dash — stop bolting when the door opens.
- Kitchen / nursery zone — keep a dog out while you cook or settle a baby.
- Hallway — temporary room divider.
- Stair top or bottom — higher stakes; plan height and latch carefully.
Your use case drives mount type (adhesive / pressure / hardware) and how tall the panel should be.
Step 2 — Measure width the right way
- Measure the clear opening width between the two vertical surfaces the gate will touch (jamb to jamb, or wall to wall).
- Measure at three heights: near the floor, mid-opening, and near the expected bracket line. Keep the smallest number.
- Note anything that steals width: thick casing, door stops, towel bars, thermostat boxes.
- If you are mounting with adhesive pads, confirm both sides have a smooth, cleanable surface.
Record: Clear width = ___ inches (narrowest).
Step 3 — Measure height for your dog
Height is not “as tall as the baby gate at the store.” Match your dog:
- Note shoulder height and whether your dog is a known jumper or climber.
- For stairs, err taller when your lease and product allow it.
- Compare your target height to the product size chart — Verymill Gate Plus lists heights such as 20″, 35″, and 47″ depending on size (see live PDP table).
Record: Target gate height = ___ inches.
Step 4 — Check depth, swing, and traffic
- Will a swinging walk-through door clear furniture or a stair tread?
- Do you need a stay-open mode for parties or carrying groceries?
- Is there a high-traffic path where a folded-flat gate (slim profile) matters more than a freestanding pen?

Step 5 — Match numbers to a size chart (example: Gate Plus)
From the live Dog Safety Gate Plus size guide:
| Size | Width (listed) | Height (listed) |
|---|---|---|
| M | 33″ | 20″ |
| L | 37″ | 35″ |
| XL | 41″ | 47″ |
| 2XL | 60″ | 47″ |
Product copy also describes adjustability across a wide opening range. Always confirm the selected variant on the product page before you pay — if your clear width sits between two sizes, choose based on the PDP’s width guidance and your narrowest measurement, not the marketing photo.

Doorway vs stairs vs RV — quick decision map
| Opening | Measure focus | Mount note |
|---|---|---|
| Interior doorway | Narrowest jamb width + height for dog | No-drill adhesive often enough for renters |
| Hallway | Wall-to-wall; watch baseboards | Fold-flat helps when gate is “off duty” |
| Stairs | Width at install line + taller height | Prefer secure hold; use optional screws if allowed |
| RV / caravan door | Exact door frame; travel fold pattern | See RV folding Gate Plus |
Common measuring mistakes
- Measuring the decorative casing instead of the clear opening.
- Ignoring baseboards that push the gate forward.
- Ordering by dog weight alone — height and behavior matter more.
- Skipping a second measurement after you move a shoe rack or plant that temporarily narrowed the hall.
- Assuming “retractable” means infinite width — still measure.
After you measure: pick the product path
- Renter / no holes: start with the no-drill Gate Plus guide angle and the Gate Plus PDP.
- Stairs / tall barrier interest: read Retractable dog gate for stairs and the Extra-Tall Metal Retractable Dog Gate page.

FAQ
Do I measure with the door open or closed? Measure the opening the gate will span — usually the clear passageway with the door open or out of the way.
What if left and right sides are different materials? Adhesive needs suitable surfaces on both sides. Uneven brick + paint may need a different mount plan.
Can I use one gate for two different openings? Only if both openings fall inside the same size’s width and height range. Measure both; do not assume.
Where should brackets sit vertically? Follow the product insert. Mark the height with painter’s tape before you commit adhesive.
