Are Your Disc Golf Discs PDGA Legal? Here’s What You Need to Know
If you’ve ever wondered whether a disc you bought (or are about to buy) is PDGA legal, you’re not alone. If you’re competing in a PDGA-sanctioned event, only PDGA-approved discs are allowed during official tournament play.
But what actually makes a disc legal for PDGA use? And what happens if it isn’t?
What Makes a Disc Golf Disc “PDGA Legal”?
In short: a disc becomes legal when the manufacturer designs a disc that meets all PDGA requirements and submits it for approval.
The process goes like this:
- The disc manufacturer sends three sample of the disc to the PDGA.
- They pay a $500 certification fee.
- The PDGA tests the disc against a set of physical and material standards of which they have set.
- If it passes, it gets added to the official list of PDGA-approved discs.
All major disc golf brands go through this process before releasing new molds to the public—especially if they want their discs to be used in tournaments.
PDGA Guidelines for Legal Discs
To be PDGA approved, discs must meet certain criteria. While the full list is extensive, here are some highlights:
- Diameter must fall within PDGA-approved ranges.
- Stiffness and flexibility must meet requirements—essentially, the disc must be flexible enough to be safe when it hits trees or, more importantly (though hopefully never), people.
- Weight must not exceed the maximum allowed for the diameter.
- Rim configuration (depth, width, sharpness) must be within approved limits.
- Materials must be safe and not pose a hazard.
- No substantial alterations—discs that are cracked, shaved, or structurally modified are illegal.
- Discs must not have stickers or reflective elements that aid visibility unfairly.
Once tested, the disc is added to the official PDGA Approved Discs List.
What This Means for You (and Discount Disc Golf)
If you’re only playing in casual rounds, you can throw whatever you want—even a plastic lid from a paint can. For you, all that really matters is that the disc does a pretty good job of almost going where you intended to throw it.
Almost all of the discs we sell are PDGA legal. However, since we’re a disc golf outlet store, our primary goal is to get and sell discs at lower prices than anyone else. We’re here for those looking for bargains—those who like lots of discs to lose for not a lot of bucks.
And one way we get discs for really cheap is by buying discs that aren’t PDGA approved. As a result, some of the inventory (we’re talking less than 1%) we receive is either not PDGA approved or not yet PDGA approved.
Occasionally, we get a disc mold manufactured by a disc golf company that didn’t pass PDGA testing, or a run where the discs came out too heavy. The manufacturers have already produced and paid for the plastic and production of these discs, so rather than sending them to the landfill, they sell them to us at a steep discount. We typically include these in our Discount Disc Golf Value Set and always make it clear in the product description when a disc is not PDGA legal.
If you plan to compete in PDGA-sanctioned tournaments, then you’ll want to make sure you know the guidelines so you can be confident that your disc is legally approved. At Discount Disc Golf, we carry a huge selection of PDGA-legal discs from all the major brands—at prices that won’t make your wallet illegal.
Your Chance to get a NOT YET PDGA Approved Disc
Do you want a disc that is not yet PDGA Approved?
Get ready for something special—DDG is about to release our very own disc! It hasn’t been PDGA approved yet and won’t be until after you’ve had a chance to test it and help us choose the name. For now, it’ll only be available through our WhatNot shows until we submit it for PDGA approval.
Final Tip: How to Check If a Disc Is Legal
Diameter Requirment
PDGA-approved discs must have a diameter between 21.0 cm and 30.0 cm, though most modern drivers, midranges, and putters fall between 21.0 and 21.4 cm. The diameter not only affects how the disc fits in your hand but also determines the maximum allowable weight for that specific mold. Discs outside this range won’t pass PDGA testing and can’t be used in sanctioned play.
-
Minimum Diameter: 21.0 cm
-
Maximum Diameter: 30.0 cm
-
Most Common Range: 21.0 cm to 21.4 cm
Rim Depth Standards
To meet PDGA approval, discs must fall within specific rim measurements. The minimum rim depth is 1.1 cm to ensure a consistent grip and feel, while the maximum rim thickness (or width) is capped at 2.6 cm (that’s WAY deeper than an Ultimate Frisbee) to maintain safety and fair play. These dimensions affect how a disc flies, feels in the hand, and how it interacts with PDGA technical standards. All discs submitted for certification must meet these requirements before they can be used in sanctioned tournaments.
-
Minimum Rim Depth: 1.1 cm — ensures the disc has a sufficient rim profile
-
Maximum Rim Thickness (Width): 2.6 cm — capped to prevent overly wide rims
Rim Thickness Requirement
The PDGA sets a maximum rim thickness of 2.6 cm, which limits how wide or sharp the edge of a disc can be. While there’s no specified minimum, most legal discs have rims thick enough to be gripped and thrown safely. Rim thickness impacts both the disc’s flight speed and safety, making it a critical measurement in the PDGA approval process.
With TPU plastics, it is very difficult for manufacturers to manufacture a disc with a very wide rim that will also meet the minimum weight threshold.
-
Minimum Rim Thickness: No minimum is defined by the PDGA
-
Maximum Rim Thickness: 2.6 cm
Weight Requirement
The maximum legal weight of a disc depends on its diameter, as outlined by PDGA guidelines. Most standard drivers and putters (around 21.0–21.2 cm in diameter) are limited to a maximum weight of about 174.3 grams, while wider midrange discs (around 21.7 cm) can go up to 180 grams. There is no minimum weight requirement, which is why many beginner or junior-friendly discs are ultra-light. While lighter discs are easier to throw and generally safer, they tend to be more affected by wind and less consistent in flight compared to heavier discs. Each PDGA-approved mold is certified with a specific maximum weight based on its diameter, and anything over that limit is not legal for sanctioned tournament play.

Frequently Asked Questions
What makes a disc PDGA legal?
A disc is PDGA legal when it’s submitted by the manufacturer to the PDGA for testing, passes all technical standards, and gets officially approved. Only approved discs can be used in PDGA-sanctioned tournaments.
What are the PDGA diameter requirements for discs?
Discs must have a diameter between 21.0 cm and 30.0 cm. Most commonly used discs fall between 21.0 and 21.4 cm.
What is the legal rim width (wing length)?
The maximum rim width allowed is 2.6 cm. There’s no official minimum, but the disc must still be safe and functional.
What is the legal rim depth?
Discs must have a minimum rim depth of 1.1 cm to ensure a consistent, safe grip.
How much can a disc weigh?
The maximum legal weight depends on the disc’s diameter. Standard discs are typically limited to around 174–180 grams. There is no minimum weight, but lighter discs tend to be less stable and more affected by wind.
Are mini discs legal to throw in tournaments?
No, mini discs cannot be thrown during PDGA play. They are only used to mark your lie and must meet PDGA size requirements. The largest size a mini marker disc can be (for marking lies) is 15 centimeters, the size of a “throwable mini” like the Doomsday Discs Dud.
Can I use a disc that isn’t PDGA approved?
Only in casual rounds. If you’re playing in a PDGA-sanctioned tournament, your disc must be on the PDGA’s approved list and meet the condition requirements.
Are stickers allowed on discs?
No. Stickers or any foreign material added to a disc are not allowed in PDGA play.
Are Dino Discs PDGA approved?
This one falls into a bit of a “gray” area. The molds used for Dino Discs were originally PDGA approved under other brand names, but they are not officially approved under the Dino Discs brand. That means Dino Discs never submitted them to the PDGA for testing or paid the required certification fee. While the disc molds themselves meet all dimensional requirements, all Dino Discs are well below the minimum weight typically required for PDGA approval. So technically, if you call the disc an “ABC Beeline,” it’s approved—but if you call it a “Tyrannosaurus Rex,” it’s not on the PDGA approved list. Dino Discs chooses not to pay the PDGA approval fee, as their discs are designed for young children who are unlikely to compete in sanctioned tournaments.
What disc molds that are NOT PDGA Legal?
Some discs are not PDGA approved—either because they never passed certification or simply never tried. Examples include the Gateway Ninja, Doomsday Discs WMD, Doomsday Discs Guillotine, and the Quest AT Turbo Putt. You’ll also want to be cautious of ultra-cheap discs sold on Amazon by unknown or overseas manufacturers, particularly those with no real connection to the disc golf community. These discs often fail to meet basic PDGA standards and are not legal for tournament play.
One interesting case is the Aerobie Epic, which has a rim width of nearly 4 cm on one side—far exceeding the current PDGA limit of 2.6 cm. While this disc would not be approved if submitted today, it was grandfathered in before the modern rim width rule was implemented, making it a rare exception to current standards.
