For Americans who think in inches: 19.69 inches is slightly shorter than the width of a standard piece of US letter paper held sideways (11 inches wide = 27.94 cm). It is clearly longer than a standard 12-inch ruler (30.48 cm) and shorter than two feet (60.96 cm). A quick way to picture it — lay a ruler flat and add about 8 inches past its end. That combined length is 50 cm.

How to Measure 50 Cm Without a Ruler
Use a Standard Sofa Cushion
Check the cushion on your couch or armchair. A standard square sofa cushion sold at Target, IKEA, and Pottery Barn measures approximately 50 cm per side. This is the most universally available reference for this exact size in most American living rooms.
Use Your Arm Length to Wrist
Let your arm hang naturally at your side. For most American adults, the distance from the shoulder joint to the wrist measures approximately 48 to 54 cm. The midpoint of that range lands right at this size.
Use a Standard Ruler Plus Two Hand Widths
Lay a 30 cm ruler flat. Add two full hand widths past the end — each hand is approximately 8 to 9 cm wide. That gives you approximately 46 to 48 cm — add one more finger width and you hit 50 cm exactly.
