The Master Pop Top Vial Comparison Guide (6–90 Dram)
Pop top vials are one of the most widely used cannabis packaging formats for flower, pre-rolls, and certain edible products. The right dram size can streamline operations, protect product quality, and keep you compliant – while the wrong size creates waste, frustration, and inconsistent branding.
This master guide walks through every major pop top vial size from 6 dram up to 90 dram, explaining capacity, best use cases, and how to compare quality between manufacturers. Use it as a reference when you’re building out a new menu, standardizing packaging across locations, or evaluating new suppliers.
What Is a Dram and Why Does It Matter?
“Dram” is a unit of volume traditionally used in pharmacy and packaging. In cannabis packaging, dram sizes are used as a shorthand for how much a container will typically hold. While actual capacity depends on flower density and product type, dram gives you a reliable way to match your packaging to your menu. 
Dialing in dram size matters because it affects:
- Cost per unit: Over-sizing containers means you pay more for plastic and shipping.
- Presentation: A properly filled vial feels substantial; an oversized container looks half-empty.
- Compliance & labeling: Consistent sizes simplify label design, printing, and application.
- Storage and logistics: The right mix of dram sizes keeps shelving and back-of-house inventory predictable.
Quick Comparison: 6, 13, 19, 30, 60 & 90 Dram Pop Top Vials
Use this table as a quick reference for how each dram size typically fits into a cannabis packaging program. Actual capacity will vary based on flower density and product form.
| Dram Size | Typical Capacity | Common Use Cases | Collection |
|---|---|---|---|
| 6 Dram | ~0.5–0.7 g flower or single mini pre-roll | Sample packs, single-serves, promotional grams | 6 Dram Pop Top Vials |
| 13 Dram | ~1 g flower | Standard 1 g SKUs, small pre-rolls | 13 Dram Pop Top Vials |
| 19 Dram | ~1.5–2 g flower | Heavier grams, mini eighths, specialty SKUs | 19 Dram Pop Top Vials |
| 30 Dram | Up to ~7 g (¼ oz) flower | Quarter-ounce SKUs, multi pre-roll packs | 30 Dram Pop Top Vials |
| 60 Dram | Up to ~14 g (½ oz) flower | Half-ounce options, bundles, larger edible packs | 60 Dram Pop Top Vials |
| 90 Dram | Up to ~28 g (1 oz) flower | Full-ounce SKUs, bulk pre-rolls, value packs | 90 Dram Pop Top Vials |
With the big picture in place, let’s break down each dram size in more detail and talk through where it fits in a real-world packaging program.
6 Dram Pop Top Vials – Micro Packs, Minis & Samples
6 dram pop top vials sit at the smallest end of the lineup and shine in situations where you want compact, controlled portions. They’re ideal when you need to
- Offer sample-sized grams or promo flower
- Package mini pre-rolls or slim single sticks
- Build small, travel-friendly edible bundles
Because the footprint is so compact, 6 dram vials are efficient for displays and in-store sampling programs. They also work well when you want to keep packaging subtle and discrete in markets that prefer a smaller container.
If you want to keep your brand visually consistent from micro packs up to full-ounce offerings, pair 6 dram vials with the larger formats listed below – all within the same preferred pop top line.

13 Dram Pop Top Vials – The Classic 1 g Standard
For many dispensaries, 13 dram pop top vials are the default container for 1 g flower SKUs. They offer enough capacity for a full gram without leaving a lot of empty space, which helps keep the presentation tight and efficient.
Best use cases for 13 dram include:
- Standard 1 g flower menu items
- Single specialty pre-rolls that don’t fit in tubes
- Small in-store sample programs and giveaways
Because they’re so common, 13 dram vials are easy to standardize across stores and teams. They also play nicely with drawer dividers, display cases, and storage trays built for short, consistent containers.
If you want a tight, predictable layout for your 1 g offerings, 13 dram is the size to start from. When you’re ready to scale up, the 19, 30, 60, and 90 dram sizes keep the same pop top look and feel while increasing capacity.

19 Dram Pop Top Vials – When You Need Just a Little More Room
19 dram pop top vials bridge the gap between 1 g containers and quarter-ounce formats. They’re ideal when your menu includes:
- Heavier grams that don’t sit well in 13 dram containers
- Small “mini eighth” offerings or dual-strain packs
- Premium grams where a slightly larger container feels more substantial
This size gives you extra room without the full height and width of a quarter-ounce vial. That makes it a smart choice for stores that want a visual difference between tiers without jumping straight from small to large containers.
Because 19 dram is not as universally used as 13 or 30, it’s a great “differentiator size” when you want certain SKUs to stand out on the shelf.

30 Dram Pop Top Vials – The Workhorse ¼ oz Container
When most people think about pop top vials, they’re picturing a 30 dram. This size is built for quarter-ounce flower, multipacks of pre-rolls, and small edible assortments. It’s tall enough to feel substantial in the hand and on the shelf, but still compact enough for dense merchandising.
30 dram vials excel when you’re:
- Standardizing all ¼ oz SKUs around a single, consistent container
- Building value multipacks of 5–10 pre-rolls
- Creating small variety packs for connoisseur menus
Because 30 dram is such a common size, it’s also a prime candidate for custom labels, tamper-evident bands, and seasonal branding programs. When you keep the container standard but swap out the label design, you can rotate promotions without changing your packaging or shelf layout.

60 Dram Pop Top Vials – High-Capacity ½ oz Packaging
60 dram pop top vials step up into the half-ounce space. Here, capacity matters as much as presentation. The container needs to feel substantial enough for a ½ oz purchase, but still be comfortable to carry and easy to stack in back-of-house storage. 
60 dram is a natural fit when you’re:
- Offering ½ oz flower as part of a “value” or “bulk” menu
- Creating larger pre-roll or edible bundles
- Building club or subscription boxes that require more volume
This size is also common for operations that package for both recreational and medical menus, because the larger footprint leaves plenty of room for compliance labels, warning icons, and dosing information.

90 Dram Pop Top Vials – Full Ounce, Bulk & Value Packs
At the top end of the lineup, 90 dram pop top vials are built for full-ounce SKUs, bulk flower offerings, and larger multi-unit bundles. If your brand emphasizes value, ounces, or “stock up and save” programs, 90 dram will play a central role in your packaging strategy.
Common uses for 90 dram include:
- Full-ounce flower containers for value shoppers
- Bulk pre-roll packs or mix-and-match ounce bundles
- Large edible assortments where you want a single, sturdy container
Because these vials are larger, it’s especially important that they’re made from durable, consistent plastic with a closure that won’t loosen under the added product weight. This is where a preferred line with strict quality control makes a real difference versus “whatever’s cheapest.”

How to Evaluate Pop Top Quality Beyond Size
Dram size is only half the equation. Two vials can be the same size but perform completely differently in the real world. When you compare suppliers, focus on these quality signals:
- Closure consistency: Lids should snap closed with a firm, repeatable feel across the entire case.
- Wall strength: The container should resist cracking under normal squeezing and handling.
- Odor and light control: Opaque options should support discretion and protect flower from light.
- Label compatibility: Walls should hold labels flat without bowing, bubbling, or peeling.
- Child-resistance: The mechanism should be difficult for children yet intuitive for adults.
MJ Wholesale’s preferred pop top line is built with these requirements in mind, giving you a consistent experience from 6 dram up to 90 dram – no matter which dram size you land on for each SKU.
Building a Cohesive Pop Top Program
The most successful operations use dram sizes strategically instead of randomly picking containers. A simple way to start is:
- Choose one standard size for 1 g (often 13 dram).
- Choose one standard size for ¼ oz (often 30 dram).
- Choose one standard size for ½ oz and ounce (60 and/or 90 dram).
- Use 6 dram and 19 dram as flexible “specialty” sizes.
Once you commit to those standards, everything else gets easier: label printing, online product photos, shelf planning, and inventory management.
When you’re ready to upgrade or standardize your pop top lineup, start by dialing in the dram sizes that best match your menu, then source them from a supplier that treats packaging as seriously as you treat your product.
