Quick Answer: Toyota Supra Wiper Sizes by Generation
Although Supra wiper sizes vary considerably by generation, you’ll generally find clear standard fits to guide replacement. You’ll match 2022 GR Supra with a 22″ driver and 21″ passenger blade, both using a 22mm Push Button Wide attachment; rear blades commonly measure 17″. Earlier generations shift: 1989–1993 models use roughly 18″/18″ with flat or standard hook fits, while 1993–1998 models move to about 21″/20″ accommodating retrofit flat and hook options. You’ll verify fit by model year before buying to avoid mismatches. Apply disciplined wiper maintenance tips: inspect blades for cracking, replace annually, and carry correct spares. Schedule seasonal checks to clear salt, ice, and debris so visibility—and your freedom to drive—remains uncompromised.
Exact Wiper Blade Sizes : 1985, 1989–1993, 1993–1998, 2019
You’ll want exact measurements for each Supra generation to guarantee proper fit and function when replacing blades. For 1985 models you’ll need OEM-specific non-removable blades—aftermarket options are limited, so source exact replacements. For 1989–1993, both driver and passenger blades are 18 inches and accept retrofit flat or standard hook fits. For 1993–1998, use a 21-inch driver and 20-inch passenger, compatible with flat and standard hook retrofits. From 2019 onward, fit a 22-inch driver and 21-inch passenger using a push-button flat attachment. Correct sizing preserves visibility and performance across conditions.

How to Measure Supra Wipers: Blades, Arms, and Attachment Diameter
When replacing Supra wipers, measure blade length from the tip to the mounting point with a tape measure to confirm the correct 22″ driver and 21″ passenger sizes on the 2022 GR Supra. Check the arm post diameter—many Supra models use different, sometimes non-removable arms—so confirm a 22 mm push-button wide fitting on the 2022 model or the specific post size for older years. Match the new blades and attachment type to those measurements to guarantee secure fit and proper wiping coverage.
Measuring Blade Lengths
Start by measuring the length of each existing wiper blade from tip to tip—excluding the attachment—to confirm the correct sizes for your Supra (for example, the 2022 GR Supra uses a 22″ driver and 21″ passenger blade). You’ll measure straight along the rubber edge, record each side, and compare to model specs before replacement. Use this approach to free yourself from guessing and guarantee reliable visibility.
- Measure blades flat on a table to avoid curvature error.
- Note year-specific differences (e.g., 1985 Supra driver 16–17″, passenger 13″).
- Compare measured lengths to manufacturer listings for fitment.
- Keep a log for wiper maintenance tips and seasonal blade care routines.
- Inspect rubber condition while measuring to decide immediate replacement.
Checking Arm Post Diameter
After you’ve measured blade lengths, check the wiper arm post diameter so replacement blades fit the attachment securely. Use calipers or a ruler to take an accurate arm post measurement at the point where the blade mates to the arm. For a 2022 GR Supra the standard is a Push Button Wide 22mm fitting; note driver 22″ and passenger 21″ blade lengths for full wiper compatibility. For older cars like a 1985 Supra, confirm whether the arm uses a non-removable design and measure the post diameter carefully to source compatible aftermarket or OEM blades. Match both the attachment type and arm post measurement to guarantee secure installation, reliable function, and clear visibility—practical steps toward independent maintenance and liberated ownership.
Wiper Attachments Explained: Push-Button, Hook, and Adapters
Although wiper blades use several attachment systems, the Push-Button Wide (22mm) and hook styles are the most common you’ll encounter on vehicles like the 2022 Toyota GR Supra, and adapters bridge the gap when aftermarket blades don’t match your OEM fittings. You’ll want to identify wiper attachment types before buying so you don’t end up with incompatible blades. Hook fittings offer secure, tool-free installs; Push-Button Wide gives a standardized, quick snap-on. Adapters convert between styles, preserving choice and freeing you from OEM-only options. Always confirm vehicle compatibility and arm post diameter to avoid performance loss.
