Best 90° Corner Guards: Easy Buyer’s Guide for Home and Office

Scuffed walls, chipped paint, and cracked plaster — it’s a common sight in busy UK homes and offices, especially around wall corners. Whether it's from trolleys in the hallway, kids rushing by with toys, or furniture being moved around, wall corners take the brunt of everyday wear and tear. That’s exactly where 90° corner guards come in — the simple but smart way to protect your interior spaces.

A 90° corner guard is a protective trim designed to shield the sharp edges of wall corners from damage. Since most interior corners in UK buildings are built at a standard 90-degree angle, these guards fit snugly and provide a discreet but effective layer of protection. They're a common choice in both residential and commercial environments — from family homes and rented flats to hospitals, offices, and schools. But choosing the right 90° corner guard isn’t just about grabbing the first one you find online. The ideal pick depends on where you’ll use it, how much traffic the area gets, what material works best, and whether you prefer a screw-fixed or self-adhesive solution. Plus, there are options now that match your decor — from wood-effect finishes for cosy interiors to anthracite grey trims for a more modern look.

In this guide, we’ll break down everything you need to know about choosing the best 90° corner guards for your space. You’ll discover the top types available in the UK market, how they differ, where to use them, and how to install them — including some of the best product options like the PVC 90° Corner Trim, 5m Flexible PVC Self-Adhesive Protector, and Anthracite Decorative RAL 7016 Angle Edging.

Let’s get started and help you protect those corners — stylishly and smartly.

Understanding 90° Corner Guards

Wall corners are one of the most commonly damaged areas in both homes and commercial buildings. It only takes a slight knock from a chair, vacuum cleaner, suitcase, or delivery trolley to leave scuff marks, chipped plaster, or paint flakes. This is where 90° corner guards become incredibly useful — acting as a protective barrier for the most vulnerable angles in your space.

What Are They & How Do They Work?

A 90° corner guard is a trim or moulding designed specifically to cover and protect right-angle (90-degree) external corners on interior walls. Most UK homes and offices are built with these standard 90-degree corners, making these guards a universal fit.

They’re typically made from materials like PVC or plastic and come in various finishes — plain, decorative, self-adhesive, or rigid — depending on your needs. Once applied, they absorb everyday knocks, preserve the wall’s integrity, and reduce the need for ongoing repairs.

Where Are They Used Most?

Here’s where 90° corner guards make the biggest difference:

• Homes: In hallways, near staircases, kids’ rooms, and kitchens — basically, any spot where foot traffic or furniture regularly brushes walls.

• Offices: Especially in corridors, entrances, break rooms, and around meeting spaces.

• Rentals: Tenants use them to prevent damage and avoid costly deductions from deposits.

• Public spaces: Schools, hospitals, retail stores — anywhere with high movement and sharp corner exposure.

Why 90° Is the Most Needed Size

Most internal corners in the UK are constructed with a 90° angle. That’s why this size is the standard and why it’s so important to get a trim that fits snugly and securely. While some areas (like columns or odd architecture) may need custom angles, a 90° corner guard is the default option for most UK properties.

Best 90° Corner Guard Types & When to Use Each

Not all wall corners are exposed to the same kind of wear and tear, which is why there’s no one-size-fits-all solution. Whether you’re kitting out a busy office corridor or safeguarding your hallway at home, the type of 90° corner guard you choose matters.
