Rectangle Picture Frame 40×50 cm

Picture Frame 40×50 cm – The Go-To Size for Art Prints and Posters

Walk into almost any poster shop or browse any online art print store, and you’ll see one size again and again: 40×50 cm. It’s big enough to make an impact on the wall, yet easy to fit into living rooms, bedrooms, hallways and offices. Our picture frame 40×50 cm is made for this popular size, so your new print fits perfectly the moment it arrives.

Each frame is made from sturdy MDF, glazed with clear HD plexiglass and available in black, white, oak or rustic. It hangs in portrait or landscape, ready for botanical prints, typography posters, travel art or your own photos.

Why a Picture Frame 40×50 cm Is So Popular

The 40×50 cm size has a 4:5 shape, a classic proportion that has been used for portraits and artwork for generations. That gives it some real advantages:

• Fits ready-made prints. Many UK and European art print shops sell 40×50 cm as a standard size, so there’s no trimming or hunting for a custom frame.
• Perfect for portraits. The 4:5 shape is the same as a classic 8×10 inch photo, ideal for people, pets and close-ups.
• Matches Instagram portrait posts. Photos and designs made for Instagram’s tall portrait format share the same 4:5 shape.
• Gallery-wall friendly. It’s a natural centrepiece size, with plenty of smaller frames that pair well around it.

Getting Your Print Right

If you’re printing your own photo or design for a picture frame 40×50 cm, a few simple checks make all the difference:

1. Choose your image. A portrait, a landscape in portrait orientation, or a piece of digital art.
2. Crop to 4:5. Most photo apps include a 4:5 preset. If your photo was posted to Instagram in portrait format, it’s already the right shape.
3. Check the resolution. Aim for an image at least 3,000 pixels wide. Original photos from modern phones and cameras are fine, but images downloaded from social media are usually too small to print well at this size.
4. Order a 40×50 cm print. It’s a common size at online photo labs. Then open the back of the frame, add your print and close it up.

Tip: when buying art prints online, double-check the listing says 40×50 cm and not 16×20 inches. They sound similar but aren’t quite the same size.

Ideas for Your Picture Frame 40×50 cm

• Botanical and nature prints. Leaves, flowers and plant illustrations bring a calm, natural feel to any room.
• Typography and quote posters. Favourite sayings, song-inspired designs and city prints look sharp in a crisp frame.
• Travel and map art. Celebrate a favourite city or holiday destination with a stylish print.
• Family and pet portraits. The 4:5 shape is made for faces, framing people and pets beautifully.
• Kitchen and dining room art. Food illustrations and vintage-style posters add personality to dining spaces.
• Kids’ bedroom prints. Alphabet charts, animal illustrations and space posters brighten up young rooms.

Pairing With Other Sizes

A picture frame 40×50 cm is the ideal anchor for a gallery wall. The 10×8 inch rectangle frame shares the same 4:5 shape, so a large print and a few smaller ones look perfectly matched together. For a mid-sized companion, try the 12×16 inch rectangle frame. If your print is 16×20 inches rather than 40×50 cm, the 20×16 inch rectangle frame is the right choice.

Built for Everyday Display

MDF is made by pressing fine wood fibres into a dense, smooth board. It stays straight and stable, resists warping and gives an even base for each colour finish, so your frame keeps its crisp look year after year.

Every picture frame 40×50 cm is fitted with HD plexiglass rather than glass. It’s clear enough to show your print’s colours and fine details naturally, and because it’s lighter and shatter-resistant, it’s a safer choice for children’s rooms, hallways and busy family homes. Remember to peel the protective film off both sides before adding your print.

Choosing a Finish

Each finish of the picture frame 40×50 cm gives your print a different personality:

Black has a fine wood-grain texture that looks bold and modern, perfect for typography, line art and black-and-white photography.

White is smooth and plain. It’s light and fresh, ideal for botanical prints, Scandinavian-style rooms and pastel artwork.

Oak has a warm, natural grain that pairs beautifully with nature prints, map art and wooden furniture.

Rustic has a weathered, textured grain that adds character to vintage posters, kitchen art and farmhouse-style homes.

Care Tips

Dust the frame with a soft, dry cloth. Clean the plexiglass with a microfibre cloth and a little mild soapy water, avoiding kitchen roll and household glass sprays, which can scratch or cloud acrylic. If your picture frame 40×50 cm hangs opposite a sunny window, keep an eye on your print, as strong daylight can fade colours over time.

Frequently Asked Questions

Will a poster from an online art print shop fit a picture frame 40×50 cm?

Yes, as long as the print is listed as 40×50 cm. It’s one of the most common print sizes, so it will fit perfectly.

Is 40×50 cm the same as 16×20 inches?

Not quite. 16×20 inches is about 40.6 x 50.8 cm, slightly larger, so it won’t fit. Choose our 20×16 inch frame for those prints.

Is 40×50 cm the same as 50×40 cm?

Yes. It’s the same frame. The order of the numbers just depends on whether it hangs in portrait or landscape.

Will an A3 print fit?

It will fit, but A3 (29.7 x 42 cm) is much smaller, so it would leave large gaps around the edges.

Can I print my Instagram photos for this frame?

The shape matches Instagram’s portrait format, but use the original high-resolution photo from your phone. The version saved from Instagram is too small to print sharply at this size.

Is the front glass?

No. It’s HD plexiglass, which is clear, lightweight and shatter-resistant.
