FITS ONLY WHEN THE BED LENGTH MATCHES
For a 2016–2023 Tacoma, buy a mat listed for the truck's actual 5- or 6-foot bed—not merely for its model year. Westin publishes separate 5-foot and 6-foot Tacoma mats, while Rough Country independently lists its RCM688 only for 5-foot beds. The cited applications do not support using a short-bed mat as a long-bed substitute.
Compatibility snapshot
| Third-gen application | Verdict | Documented example | Required check |
|---|---|---|---|
| 2016–2023 Tacoma 5-foot bed | Use a listed 5-foot mat | Westin 50-6315; Rough Country RCM688 | Confirm the actual bed length and accessory exclusions. |
| 2016–2023 Tacoma 6-foot bed | Use a listed 6-foot mat | Westin 50-6215 | Confirm the long-bed application before ordering. |
| 5-foot mat in a 6-foot bed, or vice versa | Not supported | The cited makers publish separate applications. | Do not trim, stretch or rely on a generic marketplace title. |
A third-gen Tacoma still has two bed-mat applications
“2016–2023 Tacoma” is not a sufficient mat specification. Westin's 50-6315 bed mat is listed for the 2016–2023 Tacoma 60.5-inch bed and identifies a 5-foot bed length. Westin's separate 50-6215 mat is listed for the 2016–2023 Tacoma 73.7-inch bed and identifies a 6-foot bed length.
Those are distinct manufacturer applications. A buyer should not treat the shared Tacoma model years as permission to exchange them.
What an exact 5-foot application looks like
Rough Country's RCM688 bed mat is independently listed for a 5-foot-bed 2005–2023 Tacoma. That second manufacturer source agrees with the key buying rule: its fitment is stated by bed length, not only by model year.
For a 2016–2023 Tacoma with the 5-foot bed, a mat explicitly listed for that bed is the right purchase path. It does not, by itself, prove fitment with every tonneau-cover rail, drawer system, bed extender, or aftermarket tie-down accessory.
The 6-foot-bed answer is not “buy the 5-foot mat anyway”
For a 2016–2023 long bed, Westin's 50-6215 is the cited 6-foot application. The Rough Country source used here is not evidence for the long bed because it identifies its own product only for a 5-foot bed. That limitation matters: this guide will not turn a 5-foot listing into an unsupported 6-foot recommendation.
If the truck's bed length cannot be confirmed, pause before purchasing. Measure from the bottom of the bulkhead to the tailgate opening and then compare that result with the exact manufacturer's application. Do not trim, stretch, or rely on a marketplace title to resolve the mismatch.
Bed mats help with cargo, but do not replace securement
Westin describes its mats as heat-molded for the vehicle application and uses a ribbed surface intended to help keep cargo in place. That does not create a load rating or replace tiedowns for heavy or tall cargo. Use the truck's factory tie-downs and appropriate securement for any load that could move under braking or a turn.
Bottom line
A 2016–2023 Tacoma bed mat is a bed-length purchase: 5-foot products for the short bed, 6-foot products for the long bed. The cited Westin applications support both paths, and Rough Country independently confirms the 5-foot rule. No evidence here supports treating one bed length as interchangeable with the other. After fitment is established, use the Tacoma cargo-control guide to separate floor grip from actual load restraint.
