Poop Bag Holder That Fits Two Rolls – Sizes and What Else Goes In
The poop bag holder that fits two rolls is the 3 by 1.77 by 1.77 inch zip body. That is the Leatherius leather dog poop bag holder – distressed cowhide, metal zip, free hand-stamped name, $35 – and it is the only one of the three shapes with room for a spare roll rather than a spare roll's worth of hope.
Load it with two standard rolls and it is full. Load it with one roll and you have a genuine pocket left over, which is enough for a few treats or a single flat key. Below are the real numbers for every body in the range, so you can size it against the walk you actually do.

Dimensions and capacity, all three bodies
| Body | Size in inches | Bag capacity | What else fits | Price |
|---|---|---|---|---|
| Zip block | 3 x 1.77 x 1.77 | 2 standard rolls | Swap a roll for treats or one flat key | $35 |
| Button closure | 4 x 2.5 x 1 | 1 standard roll | A little extra space alongside the roll | $35 |
| Bone shaped | 4 x 6 | 1 standard US roll | Flat body, the roll fills it | $35 |
Why the smallest one carries the most
It looks wrong on paper. The bone is 4 by 6 inches and holds one roll, while the zip block is 3 inches long and holds two. The answer is depth. The zip body is a box at 1.77 inches in both cross-section dimensions, which is almost exactly the diameter of a standard roll, so two rolls sit end to end down its length. The bone is a flat envelope of leather with a zip across the front, generous in area and about a roll thick.
The button closure body splits the difference at 4 by 2.5 by 1 inches. One roll lies along it with room beside it, which in practice means the roll plus a folded spare bag or a couple of small treats.
Do standard US rolls fit
Yes. The bodies are sized around the common US bag roll, the kind sold in packs of 8 or 12 refill rolls, roughly 1.75 inches across. Rolls from the main refill brands are close enough in diameter that they load without forcing. The variable worth knowing is bag count per roll rather than roll size: a 15-bag roll and a 20-bag roll are the same diameter, so the holder capacity is fixed and the bag count is whatever your brand puts on a roll.
Two rolls of 15 in the zip body is about 30 bags on your leash. For most owners that is a month.

What else actually goes in
Treats are the honest second use. Swap the spare roll in the zip body for small training treats and you have both jobs covered on one hook, which is the single most common reason owners size up to the two-roll body in the first place.
A key fits if it is a flat house key on its own. A car fob does not, and a phone does not go in any of these bodies, so plan for those separately. A folded twenty and a single poo bag stashed for emergencies both fit anywhere.
None of the three has a separate compartment for a used bag. Everything in the pouch shares one space, which is worth knowing before you decide to carry treats in the same body as the roll.
Sizing to the walk
A twenty-minute street walk with one dog needs one roll and nothing else, so the button closure body is the neat answer and it stays flat against the leash. A long park day, a multi-dog walk, or a dog whose output is unpredictable is where the two-roll zip body earns its keep. Professional dog walkers moving between clients want the zip body for the same reason.
If bulk on the leash handle is your worry, the zip body is the smallest of the three by a clear margin, so the roomiest option is also the one that swings least. Our dog walking kit guide covers the rest of what goes on a leash, and sizing for small dogs and thin leashes takes the weight question further.

Two holders, one leash
Some owners of two dogs run two holders on the same leash handle, one for bags and one for treats, which works because the swivel snap hook clips onto anything with a ring or a loop. It also lets you use two colors, which is the more entertaining reason people do it. The full range of seventeen leathers sits in the poop bag holders collection.
Frequently asked questions
How many poop bags fit in a leather holder?
The 3 by 1.77 by 1.77 inch zip body takes two standard rolls, which is around 30 bags depending on your brand's count per roll. The button closure and bone shaped bodies each take one roll.
Can I fit keys in a poop bag holder?
A single flat house key fits alongside a roll in the zip body or the button closure body. A car fob or a full keyring will not, since the interior depth is sized around the bag roll.
How big is the bone shaped poop bag holder?
Four by six inches, flat, with a zip across the front and a metal grommet on the back that the bag feeds through. It holds one standard US roll and it is the most visible of the three shapes on a leash.
Will a holder bulk up my leash handle?
The zip body is 3 inches long and roughly the size of a small coin purse, so it hangs below the handle rather than adding girth to it. The button closure body is only 1 inch thick, which is the flattest option if you grip right at the hook.
