Ice bag sizes are set by each manufacturer, not by a regulation or standard, and catalogue listings name them by diameter. In the three English-style ice bag distributor listings cited below, the diameters are 6, 9 and 11 inches (about 152, 229 and 279 mm), and each listing is labelled “One Size Fits Most”. This page is a lookup for reading such listings and is general product information, not medical advice; it does not cover treating any injury.
Ice bag size chart
The rows below are copied from the product listings of one medical-supply distributor (McKesson Medical-Surgical), checked 2026-10-31. Each row is attributed to its manufacturer and model number because there is no shared size standard to cite.
| Manufacturer and model | Style | Listed diameter | Approx. mm | Size label | Material | Closure |
|---|---|---|---|---|---|---|
| Fabrication Enterprises, Relief Pak, 11-1060 | English style | 6 in | 152 | One Size Fits Most | Rubberized fabric / plastic | Plastic screw cap |
| Fabrication Enterprises, Relief Pak, 11-1061 | English style | 9 in | 229 | One Size Fits Most | Rubberized fabric / plastic | Plastic screw cap |
| Graham-Field, HT9009 | English style | 11 in | 279 | One Size Fits Most | Rubberized fabric / plastic | Large opening with plastic cap |
All three listings give the activation method as “Add Ice”, describe the bag as reusable, and show a target area of “General Purpose”. Millimetre values are the inch figures multiplied by 25.4 and rounded. Check your product’s labelling: a different brand may use a different diameter, a different shape or a different cap.
How to read the chart
“One Size Fits Most” is a label, not a measurement
Every row carries the same size label even though the diameters differ. The number that tells bags apart in these listings is the diameter, and the “one size” wording only repeats that the bag is not sold in graded sizes such as small, medium and large. Compare the diameter in the listing title, not the size field.
Diameter describes the round bag, not its capacity
The listings give a diameter and no volume. A 9 inch diameter bag is wider than a 6 inch one, but the listings do not state how much ice either holds, so do not convert a diameter into a capacity or a fill line.
How to choose a size from the labelling
The only selection facts the listings support are physical ones: the diameter printed in the product name, the closure type, the material, and whether the bag is reusable or single use. If a purchase specification or product label names a diameter and a model number, match both. The listings do not state which body area suits which diameter, so this page does not assign one; follow the instructions for use that come with the product.
What the regulation says about the device itself
Under 21 CFR 880.6050 an ice bag is “a device intended for medical purposes that is in the form of a container intended to be filled with ice that is used to apply dry cold therapy to an area of the body”, and the device may include a holder that keeps the bag in place against an external area. It is Class I (general controls) and exempt from premarket notification. If it is not labeled or otherwise represented as sterile, it is also exempt from the quality management system requirements except those on records and complaint files (21 CFR 820.35). The regulation text was checked on eCFR on 2026-10-31. The FDA product code in the openFDA classification record is KYR, listed as “Bag, Ice”, Class 1, regulation 880.6050, General Hospital panel (openFDA, checked 2026-10-31).
The regulation defines the device by what it is, not by dimensions. That is why diameter, cap style and material are manufacturer choices, and why a listing’s size wording is not a regulatory category.
Equivalence notes
- Inches to millimetres: multiply by 25.4 (6 in = 152.4 mm, 9 in = 228.6 mm, 11 in = 279.4 mm).
- Catalogue codes: the 6 and 9 inch Fabrication Enterprises listings show UNSPSC 42142111, while the 11 inch Graham-Field listing shows UNSPSC 42142108. The same product style carries different category codes across listings, so do not use the code to infer size.
Ice pack, cold pack and ice bag: common mix-ups
The regulation’s ice bag is a container you fill with ice, which matches the “Add Ice” activation method in the listings. Products sold as cold packs or gel packs are a different listing style. For how a chemical instant cold pack works, see instant cold pack ingredients. For a water bottle designed for hot or cold use and its FDA class, see the hot/cold water bottle guide. For heat devices, see moist heat packs, and for a powered cold-and-compression product see the cryotherapy cuff guide. Where an ice bag sits among other kit items is covered in items inside a first aid kit.
- Diameter is not length or width. A rectangular or collar-style bag is described by other dimensions.
- “Reusable” in a listing describes the bag, not the ice, and does not state a number of uses.
- A distributor listing reproduces manufacturer data; it is not the manufacturer’s instructions for use.
FAQ
What sizes do ice bags come in?
In the English-style listings cited here, 6, 9 and 11 inch diameters, each labelled “One Size Fits Most”. Other makers may list different sizes.
Is there a standard for ice bag size?
No size standard applies. 21 CFR 880.6050 defines the device and its Class I status but does not set dimensions, so sizes are the manufacturer’s.
What is the difference between an ice pack and a cold pack?
In the regulation an ice bag is filled with ice by the user. A cold pack listing may describe a pack with its own contents, such as gel; check the product labelling for what a given pack contains.
Is an ice bag a regulated medical device?
Yes. FDA classifies it as Class I under 21 CFR 880.6050 (product code KYR), exempt from premarket notification.
