Mazda 3 Wiper Blade Sizes

This guide is for everyday Mazda 3 owners who want to replace their windscreen wiper blades but do not know where to start. It covers every generation of the Mazda 3 listed here, from the early BK cars through to the current BP models. For each one you will find the driver side and passenger side sizes, plus the rear size where your car has a rear wiper. Everything is written in plain English, so you can walk out to your car, work out what you have, and get the right blades the first time.

Sizes differ between generations, and they also differ between the sedan and the hatch within the same generation. That means you cannot assume a blade that fits one Mazda 3 will fit another. The safest approach is to match your car to the correct generation and body style first, then use the sizes listed for that exact entry. Take a moment to check before you buy, because a blade that is too long or too short will not clear your windscreen properly.

To use this guide, find the entry that matches your car's build years and body style. Note the driver side and passenger side sizes, and the rear size if one is given for your car. Then read the notes on fitting and care so your new blades last well. If you are unsure which generation you have, the how to choose section below walks you through it step by step. Keep the guide handy whenever you need to replace a worn blade.

Mazda 3 wiper sizes for each generation

For the BP sedan, the driver side takes a 26 inch (650 mm) blade and the passenger side takes a 17 inch (425 mm) blade. This sedan has no rear wiper, so you only need to sort out the two front blades. Before fitting, lay the new blades next to the old ones to confirm they match. Take your time clipping each blade on and check it sits firmly before you lower the arm back to the glass.

The BP hatch uses a 26 inch (650 mm) blade on the driver side and a 17 inch (425 mm) blade on the passenger side. It also has a rear wiper, which takes a 14 inch (350 mm) blade. That is three blades to check in total. When you fit them, make sure each one clicks into place and sits flat against the glass. A quick test sweep afterwards will show you whether everything is seated properly.

On the BM BN sedan, the driver side needs a 24 inch (600 mm) blade and the passenger side needs an 18 inch (450 mm) blade. There is no rear wiper on this sedan, so the two front blades are all you need. Before you start, note which blade came off which arm so you do not mix them up. Fit the new blades carefully and give the arms a gentle wipe so they sit cleanly.

The BM BN hatch takes a 24 inch (600 mm) blade on the driver side and an 18 inch (450 mm) blade on the passenger side. Its rear wiper uses a 12 inch (300 mm) blade. That gives you three blades to replace when they wear out. When fitting, keep each blade straight as you slide it on so the rubber is not twisted. Then lower the arms gently onto the glass rather than letting them snap down.

For the BL sedan, the driver side takes a 24 inch (600 mm) blade and the passenger side takes a 19 inch (475 mm) blade. This sedan has no rear wiper, so you only need the two front blades. Check that each new blade is the right length for its side before fitting. Once they are on, run the wipers briefly and look for any gaps or missed patches on the glass.

The BL hatch uses a 24 inch (600 mm) blade on the driver side and a 19 inch (475 mm) blade on the passenger side. It also has a rear wiper that takes a 14 inch (350 mm) blade. That is three blades in total to keep an eye on. Fit each one firmly and make sure the rear blade rests flat against the back window. A quick check after fitting will save you trouble later.

On the BK sedan, the driver side takes a 21 inch (525 mm) blade and the passenger side takes a 19 inch (475 mm) blade. There is no rear wiper on this sedan, so the front pair is all you need. Older cars often have worn arms, so give each arm a wipe before fitting the new blade. Then press the blade on until it is secure and lower the arm gently to the glass.

The BK hatch takes a 21 inch (525 mm) blade on the driver side and a 19 inch (475 mm) blade on the passenger side. Its rear wiper uses a 14 inch (350 mm) blade. That makes three blades to replace when they start to wear. When fitting, take care not to bend the arms, and check each blade sits evenly along the glass. A short test sweep will confirm they are working well.

How to work out which Mazda 3 you have

Start by working out which generation of Mazda 3 you own. The build years are the easiest clue, and the body style matters too, because the sedan and hatch are listed separately. Check the compliance plate or your registration papers if you are not sure of the year. Once you know the years and whether your car is a sedan or a hatch, find that exact entry in this guide. Do not guess from a similar model, because the sizes differ between generations.

Next, match each side separately. The driver side and passenger side often take different lengths, so treat them as two separate jobs. Note the driver side size first, then the passenger side size, and the rear size if your car has one. Buying a pair that matches the listed sizes for your car is the simplest way to get it right. If you are ever unsure, measure your old blades and compare them with the guide before you buy.

When to replace your wiper blades

Worn wiper blades show themselves in a few clear ways. You might see streaks of water left behind after each sweep, or a smeared film that makes the glass harder to see through. Some blades squeak or judder across the windscreen, and others leave patches that never get cleared. If you notice any of these, it is a good sign the rubber has worn out and the blades need replacing.

It also pays to look closely at the rubber itself. Split, cracked or hardened rubber cannot wipe the glass cleanly, even if the blade still moves. Sun, dust and everyday use all wear the rubber down over time. Once the edge looks ragged or feels stiff, a new blade will make a big difference. Replacing them before they fail completely is easier than dealing with a sudden bad wipe in heavy rain.

Good visibility matters for safe driving. A blade that smears or streaks can leave you squinting through a blurry windscreen exactly when you need to see clearly. Rain, spray from other cars and low light all make poor wipers more dangerous. Replacing worn blades is a small job that helps you see the road properly and react in time. Do not wait for a storm to remind you.

Looking after your wipers

Looking after your wipers starts with clean glass. Dirt and grit on the windscreen wear the rubber edge down faster, so give the glass a wash regularly. Wipe the blade rubber itself with a damp cloth now and then to remove dust and grime. When you wash the car, lift the arms off the glass carefully so you can clean underneath them, then lower them gently rather than letting them snap back.

Sun and dust are hard on wiper rubber, so park in the shade where you can. Check your washer fluid regularly and top it up so you can clear the glass when you need to. If you lift the arms off the glass, do it gently and never let them spring back on their own. A little care like this helps your blades last longer and keeps your view clear.

Frequently asked questions

How do I know which Mazda 3 generation I have?

Check your build year and whether your car is a sedan or a hatch. The years and body style together point to the right entry in this guide. If you are unsure of the year, your registration papers or compliance plate will tell you. Then match that entry exactly before buying.

Why are the driver and passenger blades different sizes?

Many cars use a longer blade on the driver side and a shorter one on the passenger side. That is why this guide lists them separately. Buy each side to the size shown for your car rather than assuming a matching pair will fit.

Does my Mazda 3 have a rear wiper?

Only some entries in this guide list a rear size. If your car's entry includes one, it has a rear wiper and you should replace that blade too. If no rear size is shown for your car, then you only need the front blades.

How often should I replace my wiper blades?

Replace them when you notice streaking, smearing, squeaking or judder, or when the rubber looks split or cracked. There is no fixed schedule that suits every car, so let the condition of the blades guide you. Replacing them early keeps your view clear in the rain.

Can I fit the blades myself?

Yes, fitting wiper blades is a simple job most owners can do at home. Take care with the arms and lower them gently onto the glass. Check each blade sits firmly before you use the wipers. If a blade does not feel secure, stop and check it again.

What should I do if my new blades streak?

First clean the glass and the blade rubber, as dirt often causes streaking. If the streaks continue, check the blade is the correct size for that side and is fitted securely. Worn arms or a poor fit can also cause problems, so review the fitting before assuming the blade is faulty.
