You found the perfect 50x70 cm poster, but now you're lost in a sea of US frames measured in inches. Sizes like 18x24 or 24x36 don't seem right, turning your framing project into a frustrating puzzle. This is a common problem for art lovers.
What's the Exact Size?
Don't guess and end up with an ill-fitting frame! The key is knowing the precise conversion from centimeters to inches. Getting this number right is the first step to making your new artwork look professionally framed on your wall.
The Magic Number
Let's do the math. Using the universal conversion of 1 inch = 2.54 centimeters, we can find the exact size. A 50 cm width is 19.685 inches, and a 70 cm height is 27.559 inches. These precise numbers are crucial.
Your Frame Size Is...
For practical shopping purposes, the exact conversion is rounded. You need to look for a frame that is specifically labeled as 19.7 x 27.5 inches. This is the correct US frame size for your 50x70 cm art print.
Warning: The Common Trap
The biggest mistake you can make is buying a standard 20x28 inch frame. It sounds close enough, but it's a trap that catches many people. This common off-the-shelf size is not the right fit for your art.
Why It Doesn't Fit
A 20x28 inch frame is significantly larger than your print. It will leave an ugly gap of about one-third of an inch on all sides. Your 50x70 cm artwork will 'float' awkwardly inside instead of fitting snugly.
Size-by-Side Comparison
Let's break it down. Your art is 50x70 cm. The exact conversion is 19.685" x 27.559". The correct frame you need is 19.7" x 27.5". The trap frame to avoid is 20" x 28".
A Global Standard
Ever wonder why 50x70 cm is so popular, especially with European art? It's based on the ISO 216 international paper standard. This size is nearly identical to the B2 paper size (500 x 707 mm), making it a global favorite.
Frame with Confidence
Now you're an expert! Armed with the correct 19.7 x 27.5 inch measurement, you can skip the confusion and avoid common mistakes. Go ahead and frame your 50x70 cm masterpiece with total confidence for a perfect display in 2026.
