Chest point
Tail base
Chest point to tail base
Measure from the front point of the chest to the base of the tail. Do not include the head, nose, or tail.
Fit Guide
Measure once. Buy with a calmer kind of confidence.
Use this page when Atlas already feels like the right system and you want the final numbers, photos, entry notes, and storage details ready before checkout or support review.
Standard measurement points
The six checks that should be ready before purchase.
Use inches and centimeters if possible. Keep the dog on level ground, take each measurement twice, and write down the larger number when the result is close. Do not guess from breed averages.
Chest point
Tail base
Top of shoulder
Floor
Floor to withers
Measure from the floor to the top of the shoulder. Do not measure to the head or ears.
Left side
Right side
Widest relaxed point
Measure the widest point across the chest or hips while standing naturally, not stretched or compressed.
Natural rest
No forced crouch
How the dog settles
Note whether the dog sits upright, lies long, curls, or leans. This affects comfort liner and side-support planning.
Approach
Settle point
Step, guide, or lift
Record whether the dog can step in calmly, needs rear support, needs front support, or needs a ramp/handler plan.
Width
Depth
SUV and home footprint
Measure cargo space and the storage location at home. A product can fit the dog but still fail the routine if storage is not planned.

Fit worksheet
The purchase check that belongs right before checkout.
Use a soft tape measure. Measure while your dog is calm, standing naturally, and not stretching forward for food or attention. If your dog cannot stand comfortably, measure the closest natural resting position and send photos to support.
Measure
How to take it
How to judge fit
Current weight
Use the most recent scale weight, not an old vet record. If weight changes often, use the higher current number and note the change.
Compare this against the published Atlas support range. If your dog is near the upper limit, do not guess. Ask support before ordering.
Body length
Measure from the front point of the chest to the base of the tail while standing naturally. Do not include the head or tail.
Atlas should allow the chest and tail base to rest without being pressed into the front or rear wall. Add photos if your dog has a long body or deep chest.
Shoulder height
Measure from floor to the top of the shoulder, not the head. For tall dogs, also note whether the head stays relaxed when seated.
The side support should feel protective without forcing a crouch, twist, or high-neck position. If posture looks tense, fit needs review.
Body width
Measure the widest relaxed point across the chest or hips. Do not pull the tape tight against fur, ribs, or joints.
The dog should have enough room to settle without being wedged or forced into one posture for the whole outing.
Resting posture
Watch how your dog rests after a short walk: sitting upright, lying sphinx-style, leaning to one side, or curling.
Choose Atlas only if that natural rest can be supported calmly. Leaning dogs may need extra liner support or a slower entry routine.
Storage footprint
Measure the SUV cargo area, garage wall, hallway, or home storage zone where Atlas will live between outings.
If storage is difficult, the product may be used less often. Treat vehicle and home storage as part of the purchase decision.
Fit note builder
Build a support-ready fit note.
This does not replace the final product specifications. It gives you a clear measurement note to review before checkout or send to support when one answer feels uncertain.
Photos help
If you are unsure, take three photos before contacting support.
Side standing photo
Dog standing on level ground, full body visible from nose to tail base. This shows length and natural stance.
Resting posture photo
Dog in the position they choose when tired. This helps judge comfort, side support, and liner needs.
Entry ability note
Tell support whether your dog steps in, needs rear support, needs front support, or must be guided slowly.
Fit is not only size
Atlas must fit the dog and the person using it.
A correct fit also depends on who handles the system, where it is stored, and how the dog enters. A large dog can be inside the size range and still need a different entry plan.
- One person should be able to control the system on the surfaces you use most.
- The dog should have a calm way in before the first full outing.
- The folded system should have a planned place in the vehicle or home.
Weight is within support range
Use current weight and leave margin if your dog is close to the published limit.
Body length rests naturally
Your dog should be able to settle without being compressed at the chest or tail.
Posture looks comfortable
Look for calm sitting or resting, not a forced crouch, twist, or high-neck position.
Entry is realistic
Know whether your dog can step in, needs assistance, or needs a ramp/accessory plan.
Fit is also a lifestyle decision
Use the scenario notes when the numbers alone do not answer the question.
