How USA Pickleball Tests Paddles: Limits and Tests

USA Pickleball tests paddles against the specifications in its Equipment Standards Manual, currently Revision 3.0 (January 2025). The published limits cover size (length no more than 17 inches, length plus width no more than 24 inches), surface roughness, surface friction, gloss, and power, measured as PBCoR with a not-to-exceed limit of 0.43 since November 1, 2025. Testing runs at an independent lab, Element U.S. Space & Defense (formerly NTS). From October 1, 2026, newly submitted paddles must also pass a spin rate test capped at 2,100 RPM.

Below is each test with its limit exactly as USA Pickleball publishes it, plus what happens when a paddle already on the list is later decertified. To check one paddle, search the official USA Pickleball paddle list. For the paddles in our catalog, see our USAP status tracker.

Who does the testing

USA Pickleball's Equipment Evaluation Committee (EEC) works with testing labs at Element U.S. Space and Defense, formerly National Testing Systems (NTS). The manual says the EEC "reviews every piece of equipment submitted for testing" and has been in place since 2016 (Equipment Standards Manual, Introduction). USA Pickleball's testing history page dates the start of its equipment testing to 2015. The Board of Directors grants approval, acting on the EEC's recommendation (ESM 2.F).

For a new paddle submission, USA Pickleball currently requires nine paddles shipped to six separate locations. Submitted paddles are not returned. Normal testing takes 4 to 6 weeks, and expedited testing takes 3 to 8 business days (USAP Equipment Submission FAQ).

The paddle specifications and their limits

Size

The manual's rule 2.E.3 reads: "The combined length and width, including any edge guard and butt cap, shall not exceed 24 inches (60.96 cm). The paddle length cannot exceed 17 inches (43.18 cm). There is no restriction on paddle thickness." (ESM 2.E.3). The 2026 rulebook repeats the same limits in Rule 3.D.2 (2026 USA Pickleball Official Rulebook). Our paddle shapes guide shows how that 24-inch budget gets split between length and width, and the thickness guide covers core depth.

Weight

There isn't a weight limit. ESM 2.E.4 says: "There is no restriction on paddle weight." Rulebook 3.D.3 says the same. For how listed weights compare across paddles, see how heavy a pickleball paddle should be.

Surface roughness

Roughness is measured with a Starrett SR160 or SR300 Surface Roughness Tester or an equivalent. Each face is measured in six directions, and the six readings are averaged per face. The limits in ESM 2.E.2.a.1 are:

• Rz (average maximum height, peak to valley): average no greater than 30 micrometers, with no single reading above 33 micrometers.
• Rt (maximum height, peak to valley): average no greater than 40 micrometers, with no single reading above 44 micrometers.
• Each face of the paddle must comply on its own.

Coefficient of friction

A friction test based on ASTM D1894-14 measures "general friction characteristics regardless of surface finishing process or technology." A paddle passes with a maximum kinetic coefficient of friction of 0.1875 or less (ESM 2.E.2.a.2). USA Pickleball's history page says it added the friction test in 2018, calling friction "a significant contributor to spin."

Gloss (reflection)

Paddle faces and edge guards "shall not have any Measurement exceeding 80 GU." Gloss is measured at 60 degrees with a surface gloss meter (ESM 2.E.2.b).

Power: PBCoR

PBCoR stands for Paddle/Ball Coefficient of Restitution. It measures the "trampoline effect," which USA Pickleball defines as the paddle surface deforming and then rapidly returning to shape, "effectively 'springing' the ball off the paddle" (USA Pickleball, Paddle Certification Updates). USA Pickleball's rulemaking notice NPRM 24-002 says the test is based on ASTM F2219-14, a standard for measuring high-speed bat performance. It says typical test conditions are "60 MPH for a test ball shot with an air cannon at a paddle," and that PBCoR is derived from the ball's inbound and outbound speeds (NPRM 24-002, PBCoR Testing).

The not-to-exceed limits in ESM 2.E.6.f are 0.44 effective November 1, 2024, reduced to 0.43 effective November 1, 2025. The NPRM says paddles submitted for testing after November 1, 2024 must meet the PBCoR requirement.

Deflection

Before PBCoR, NPRM 24-002 says, USA Pickleball's tests relied on "a static deflection test that measures the stiffness of the paddle face," based on a static 3-point beam stiffness test. That test was used as a stand-in for power. The notice says it was "best suited for paddles with uniform construction" and could not fully capture newer designs, and that is why the dynamic PBCoR test was added. The history page also describes a 2019 "cantilever beam screening function, which evaluates paddle rigidity." The current manual doesn't publish a numeric deflection limit, so we don't give one here.

Construction and features

Paddles must be made of "rigid, non-compressible material" (ESM 2.E.1). Rule 2.E.6 prohibits rubber, sandpaper characteristics, textured anti-skid paint, springs or other trampoline materials, "electrical, electronic, or mechanical assistance of any sort," and moving parts that increase head momentum. Vibration dampers are allowed. The paddle must also be marked with its brand and model name or number and the "USA Pickleball Approved" seal or text treatment (ESM 2.E.7; Rulebook 3.D.1).

What changes on October 1, 2026: the spin rate test

In an update published July 8, 2026, USA Pickleball announced a spin rate test with an implementation date of October 1, 2026 and a maximum spin rate of 2,100 RPM. The same notice says the upper thresholds for surface roughness and coefficient of friction will be "replaced by a measurement of record." As we read it, roughness and friction will still be measured and recorded for new submissions, but the spin cap replaces them as the pass/fail limit. From October 1, 2026, "all paddles submitted for certification must achieve a measured spin rate of 2,100 RPM or less." The notice also says "all certified paddles must comply with the equipment standards that were in effect at the time of certification" (USA Pickleball, Spin Rate Test update). As of today, the Equipment Standards Manual posted on USA Pickleball's site is still the January 2025 revision, which lists the roughness and friction limits above.

Approval isn't a one-time event

Under ESM 2.F.2, manufacturers "are subject to ongoing compliance testing" to make sure production paddles match the one that was certified. Rule 2.F.2.a says paddles must stay compliant "over the entire useful life of the paddle," including any "degradation to benefit," such as a paddle getting livelier as it breaks in. USA Pickleball's FAQ says it "inspects market samples to confirm compliance" (USAP FAQ).

USA Pickleball has also announced field testing at events. Its January 16, 2026 announcement says paddles at participating Golden Ticket tournaments would be tested on site. Initial testing would cover "coefficient of friction, deflection, and weight/balance properties," with PBCoR and spin added in future phases (USA Pickleball field-testing announcement).

What "delisted" or "decertified" means for you

You'll see words like delisted, banned or rescinded. USA Pickleball's own pages say "decertified" or "removed from the USA Pickleball approved paddle list." Its FAQ says equipment "is decertified when it fails to meet the conditions of its certification," including inaccurate disclosures or inconsistent production. Paddles that exceed the PBCoR threshold "are now in violation of rule 2.E.6.f and are decertified." One recent example: in May 2026 USA Pickleball said a paddle was removed from the approved list after it was found to exceed the surface roughness standard, and the maker acknowledged that the production version differed from the one submitted (USA Pickleball statement, May 28, 2026).

What it means in practice:

• Recreational play is unaffected. The FAQ says: "The decertification only applies to sanctioned tournament play. Players can still use the paddles for recreational play."
• There may be a notice period. The FAQ describes a "sunset period" between the announcement and the decertification date. It's typically 18 months, though USA Pickleball used a shorter timeline for the PBCoR decertifications. ESM 2.F.1 also refers to 18 months' notice for revoking approval of equipment that has materially changed. USA Pickleball's December 2024 update set July 1, 2025 as the sunset date, for sanctioned play only, for the first group of paddles that exceeded the PBCoR threshold (Paddle Certification Updates).
• Checking is your job. Rulebook 18.A says players "must confirm that their paddle is approved and listed on the USA Pickleball Approved Paddle List." If a non-compliant paddle is found before a match, you switch with no penalty. If it's found during a match, a match forfeit is imposed. If it's found after the match, the results stand (Rulebook 18.A.1 to 18.A.3).
• Refunds depend on the brand. The FAQ says refund or exchange policies "depend on the manufacturer."

USA Pickleball also publishes a Paddle Compliance Report. It lists statuses such as "Under Investigation," "Removed from USAP Approved List" and "Compliance Issue Resolved."

How to check your own paddle

Search the official paddle list by brand and model. Then check the compliance report for any open issue. Our USAP status tracker does this cross-check for every paddle in the PickleSwaps catalog, and entries link back to USA Pickleball's own record where we have one. It only covers our catalog, though, and USA Pickleball's list is the one that counts. For a step-by-step walkthrough, read is my pickleball paddle approved? Pro events sanctioned by UPA-A use a separate certification. USAP vs UPA-A certification explains the difference, and our UPA-A tracker covers our catalog.
