Letter Plates

Q: What is a sprung letter plate?

A sprung letter plate has a flap fitted with an internal spring that automatically returns it to a closed position after use. This helps reduce draughts, prevents rattling in windy conditions, and enhances thermal efficiency. Sprung letter plates are the most popular design for traditional timber doors.

Q: Can I get a letter plate with a knocker?

Yes — we offer letter plates with integrated knockers in a variety of traditional and modern finishes.

Q: What sizes are available?

Most letter plates are 10 x 3 inches (254 x 76mm) or 12 x 4 inches (305 x 102mm), with the larger size suited to A4 post or newspapers. We offer many other sizes as well — if you need something specific, send us the overall dimensions, aperture size, and bolt fixing centres, and we’ll help find a suitable option.

Q: Can I match it with other hardware?

Yes. You can coordinate your letter plate with matching door handles, centre door knobs, escutcheons, cylinder pulls, and door knockers in complementary finishes.

Letter Plates for Timber Doors – Sprung, Gravity & Knocker Options

Explore our hand-picked range of letter plates for timber doors, including sprung flap, gravity flap, and integrated knocker designs. Choose from traditional or modern styles to suit every entrance.

Classic Designs, Built to Perform

Sprung flap letter plates are the most popular choice for UK homes with timber doors. Fitted with internal springs, they return to a closed position automatically — keeping draughts, noise, and weather firmly outside. For more traditional settings, gravity flap letter plates offer an elegant, timeless solution often used in period properties.

Letter Plates with Knockers and a Wide Range of Sizes

If space is limited or you want a cleaner look, consider a letter plate with knocker — a space-saving 2-in-1 option that adds both function and flair. Sizes include the two most popular UK standards: 10” x 3” (254 x 76mm) and 12” x 4” (305 x 102mm), with larger sizes ideal for newspapers or A4 post. We also offer a wide variety of other sizes. If you can’t find what you need, just send us your required overall dimensions, aperture size, and fixing centres — we’ll help you find the right match.

For a neat internal finish, pair your front plate with a Letter Tidy. Or explore other options in the Letter Plates & Covers collection, including Telescopic Letter Plates.

Frequently Asked Questions

What is a sprung letter plate?

A sprung letter plate has a flap fitted with an internal spring that automatically returns it to a closed position after use. This helps reduce draughts, prevents rattling in windy conditions, and enhances thermal efficiency. Sprung letter plates are the most popular design for traditional timber doors, offering a secure, reliable, and discreet way to receive post while maintaining your home's appearance and comfort.

What is a gravity flap letter plate?

A gravity flap letter plate uses the weight of the flap to naturally fall shut after use. It’s a traditional style often seen on older timber doors, especially in period properties. However, gravity flap letter plates aren't as widely used today, and there are fewer style and finish options available compared to sprung flap models. One downside is that the flap can be caught by the wind, which may cause draughts or lead to the flap banging noisily against the door in strong weather.

Can I get a letter plate with a knocker?

Yes — we have letter plates with integrated knockers in multiple finishes.

What sizes are available?

Most letter plates are 10 x 3" (254 x 76mm) or 12 x 4" (305 x 102mm), with the larger size ideal for A4 post or newspapers. We do offer many other sizes too — if you can't find what you're looking for, just send us an email with the overall dimensions, aperture (letter slot) size, and bolt fixing centres, and we’ll check what we can supply.

Can I match it with other hardware?

Yes. You can coordinate with door handles, escutcheons, and centre door knobs.
