Replacing the windshield with Škoda Octavia - a task that every owner faces sooner or later. From a crack after a stone hit to complete destruction during an accident - the reasons may be different, but the result is the same: you need to know exactly glass dimensionsso as not to make a mistake with the purchase. An error of even a few millimeters will lead to installation problems, leaks or squeaks when moving.
In this article we have collected current data on windshield dimensions for all generations Octavia (A4, A5, A7, A8), including restyled versions and modifications with a panoramic roof. You'll learn how to properly measure glass yourself, where to find original part numbers, and why cheap alternatives can cost more in the long run. And for those who are planning a replacement with their own hands, we will provide step-by-step instructions with nuances that the services are silent about.
Why is it important to know the exact size of your windshield?
It seems that choosing glass according to your car model is a simple task. But in practice, even official dealers make mistakes. Here are three key reasons why The sizes must match perfectly:
- 🔧 Installation problems: glass that is 5–10 mm larger or smaller will not fit into the grooves of the body. Craftsmen will have to “adjust” it by force, which is fraught with chips or cracks already at the installation stage.
- 💧 Leaks and corrosion: If the glass does not fit tightly to the seal, moisture will penetrate into the interior, and over time, the metal under the windshield will begin to rust.
- 🚗 Review Distortion: non-original glass often has a different curvature, which leads to optical distortion, especially noticeable at night or in the rain.
In addition, on Octavia third and fourth generations (A7, A8) glass with integrated sensors (rain, light, road surveillance cameras). If you buy glass without taking these elements into account, you will have to reinstall the sensors from the old one, which will increase the cost of work by 30–50%.
⚠️ Attention: On restyled versions Octavia A5 FL (2010–2013) and A7 FL (2017–2020) the shape of the glass in the wiper mounting area was changed. Make sure there is a prefix in the catalog number FL (facelift).
Windshield sizes by generation Škoda Octavia
Below is a table with glass dimensions for all generations Octavia, including modifications with a panoramic roof (Panorama) and taxi versions (Taxi). The data is relevant for European and Russian versions (left-hand drive/right-hand drive).
| Generation | Years of manufacture | Glass size (W×H), mm | Catalog number (original) | Notes |
|---|---|---|---|---|
| Octavia A4 (1U) | 1996–2004 | 1430×800 | 6U6 845 011/012 | For sedan and station wagon. Version 012 — with a tinted stripe. |
| Octavia A5 (1Z) | 2004–2013 | 1450×820 | 1Z6 845 011 B | Standard glass. For RS and Scout - another number: 1Z6 845 011 C. |
| Octavia A5 FL (facelift) | 2010–2013 | 1450×825 | 1Z6 845 011 D | The shape in the wiper area has been changed. Incompatible with pre-restyle glass! |
| Octavia A7 (5E) | 2013–2020 | 1480×850 | 5E6 845 011 A | Basic version. For Panorama — 5E6 845 011 B (height 830 mm). |
| Octavia A8 (NX) | 2020–present | 1500×860 | 5EE 845 011 | Glass with integrated camera Front Assist. For iV (hybrid) - separate room. |
Please note: on Octavia A7 and A8 with a panoramic roof, glass with reduced height (830–840 mm instead of standard 850–860 mm). This is due to the changed roof geometry. If you buy regular glass, it will not fit into the opening!

How to measure your windshield yourself?
If you are not sure about your generation Octavia or the car has undergone body repair, it is better to measure the glass manually. For this you will need:
- 📏 Tape measure or ruler (minimum 1.5 m).
- 📝 Notepad for notes.
- 🧲 Magnet (optional, to check the presence of a metallized layer).
Procedure:
- Measure width glass along the top edge (from left to right corner).
- Measure height from the top edge to the bottom edge in the center.
- Check radius of curvature: Place a ruler on the glass in several places. If the gap is more than 2 mm, the glass has a complex geometry (relevant for A8).
- Inspect the edges for cutouts for sensors (rain, light, camera).
⚠️ Attention: On Octavia A7 and A8 glass has asymmetrical shape - the left and right sides differ in curvature. When measuring, take this into account, otherwise the new glass will not fit into the grooves.
☑️ What to check before buying glass
Original vs analogues: what to choose for Octavia?
Glass from the official manufacturer (Saint-Gobain Sekurit or Pilkington) guarantees a perfect fit and long service life, but its price can exceed 30–40 thousand rubles. Alternatives are cheaper, but not always safer. Let's look at the pros and cons of each option:
| Glass type | Pros | Cons | Average price (2026) |
|---|---|---|---|
| Original (Škoda) | Perfect fit, no distortion, full sensor compatibility. | High cost, long wait (if made to order). | 35 000–50 000 ₽ |
| OEM analogues (Sekurit, Pilkington) | The quality is the same as the original, but 20–30% cheaper. | There may be no cutouts for sensors (check!). | 25 000–35 000 ₽ |
| Budget analogues (XYG, BOS) | The price is 2-3 times lower than the original. | Risk of distortion, poor sealing, short service life. | 10 000–18 000 ₽ |
If your budget is limited, choose OEM analogues from Sekurit or Pilkington — they supply glass to the conveyor Škoda, so the quality is identical to the original. Avoid Brands XYG and BOS for Octavia A7/A8 - they often have problems with sensors Front Assist and Lane Assist.
Before purchasing, check the glass for availability ECE R43 labels (European safety certificate). Without it, glass may not withstand the impact of an accident and crumble into dangerous fragments.
Step-by-step instructions for replacing a windshield
If you decide to replace the glass yourself, follow this algorithm. Opening hours: 3–4 hours (with an assistant). Cost of materials: 2,000–3,000 rubles (glue, primer, napkins).
Required tools:
- 🔨 Knife for cutting glue (special, with a hook).
- 🧴 Primer and glue for glass (3M, Sika or Teroson).
- 🧤 Gloves and safety glasses.
- 🚗 Jack and stands (for fixing the hood).
Procedure:
- Remove the windshield wipers, plastic covers under the windshield, and rearview mirror.
- Using a glue cutting knife, carefully separate the glass from the body, starting from the top corner. Don't push too hard - You can damage the paint!
- Remove old adhesive and clean the grooves with degreaser wipes.
- Apply primer to the body and new glass (according to the glue instructions).
- Install the glass, starting from the bottom edge, and secure it with tape for 1-2 hours.
- Do not operate the vehicle for 12–24 hours (glue polymerization time).
⚠️ Attention: On Octavia A8 when replacing glass is required Front Assist camera recalibration! Without this, the emergency braking system will not work correctly. For calibration you need a diagnostic scanner (VCDS or ODIS).
What happens if you don't wait for the glue to polymerize?
If you start driving earlier than 12 hours, the glass may move due to vibration, which will lead to leaks. In the worst case, it will fly out during sudden braking or an accident.
Where to buy a windshield for Octavia with a guarantee?
The choice of where to buy depends on your budget and quality requirements. Let's look at proven options:
- 🏢 Official dealer Škoda: 1-2 year warranty, but the price is 30-50% higher than the market price. Suitable if you need an original with full responsibility.
- 🛒 Specialized stores: For example, Auto glass, Vector or Glass Service. Here you can find OEM analogues at a price 20% lower than the dealer.
- 🌍 Online stores: Exist.ru, Autodoc, Emex. It’s convenient to compare prices, but the risk of running into a fake is higher. Always check reviews!
- 🔧 Glass replacement services: Many offer turnkey glass with installation. The price often includes a material discount.
When purchasing online, be sure to check:
- Compatible with VIN number your car (can be checked on the website VinInfo).
- Availability ECE R43 certificate (must be in the description or in the photo).
- Possibility of return if the glass does not fit.
Buy glass only from sellers with a rating of at least 4.8 and a number of reviews of 100 or more. This minimizes the risk of running into a fake.
Common replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to leaks, squeaks or repeated replacements. Here are the most common of them:
- Using the wrong glue. For Octavia A7/A8 you need an adhesive with high elasticity (for example, SikaTack Drive), since the body of these models has increased rigidity.
- Incomplete cleaning of grooves. Residues of old glue or dirt will cause poor adhesion. Use a special cleaner (3M 08984).
- Incorrect installation of seal. On Octavia A4 and A5 The seal comes separately from the glass. If you twist it, there will be leaks.
- Ignoring sensor calibration. On A8 After replacing the glass, you must calibrate the camera
Front Assistand a rain sensor.
To avoid these problems, keep an eye on temperature in the garage (optimally 18–22°C) and take your time. If you have never changed glass before, it is better to practice on an old car or watch a video instruction for your model Octavia.
FAQ: Answers to frequently asked questions
Is it possible to install a windshield from Octavia A7 on A5?
No, that's impossible. The glass differs in size (1480×850 mm for A7 versus 1450×820 mm for A5) and the shape of the fastenings. Even if it is physically possible to insert glass, it will not be sealed, and the sensors (if any) will not match.
How to check if the glass is original on my Octavia?
Original glass Škoda have:
- Logo Škoda or VW Group in the bottom corner.
- Marking
ECE R43and batch number. - Smooth edges without burrs (analogs often show traces of casting).
You can also check the catalog number with ETKA.
How much does it cost to replace a windshield at a service center?
Cost depends on generation Octavia and glass type:
- Octavia A4/A5: 8,000–15,000 rubles (work + analogue glass).
- Octavia A7: 15 000–25 000 ₽.
- Octavia A8: 25,000–40,000 rubles (due to sensor calibration).
Original glass will cost 10–15 thousand rubles more.
Is it possible to drive with a cracked windshield?
Technically yes, but it's dangerous:
- Crack longer than 10 cm impairs visibility (fine under Article 12.5 of the Administrative Code - 500 rubles).
- In case of an accident, the glass may crumble, which will lead to injury.
- On Octavia A7/A8 crack in sensor area disables driver assistance systems.
If the crack is less than 5 cm and is not in the driver's line of sight, you can temporarily seal it with tape, but it is better to replace the glass as soon as possible.
How to remove the windshield without damaging the body?
The main rule is take your time and use the right tools:
- Remove all plastic elements around the glass (wipers, trim).
- Using a glue cutter, carefully cut the caulk around the perimeter, starting at the top corner.
- Have a helper support the glass from the outside to prevent it from falling.
- After removal, clean the grooves from old glue without abrasives (use a plastic scraper).
On Octavia A8 be careful with camera wires Front Assist — they are attached to the glass and can come off!
