A 109 cm TV is a 43-inch TV. The figure refers to the diagonal of the screen panel. To convert, divide 109 by 2.54 (centimetres per inch): 109 ÷ 2.54 = 42.91, which rounds to 43 inches. A 43-inch screen has an exact diagonal of 109.2 cm (43 × 2.54), so the 2 mm difference between "109 cm" and the true measurement is simply a result of rounding. European and metric-market retailers sometimes list this size as 109 cm; inch-based markets list it as 43 inches — they are the same screen.
A 109 cm (43-inch) TV with a standard 16:9 aspect ratio is 95.2 cm wide and 53.5 cm tall, measuring the screen only. The full unit — including the bezel — is typically 97–102 cm wide depending on the model. Slim-bezel designs may be closer to 97 cm total width; budget models with wider bezels can reach 102 cm. For fitting into a specific shelf or media unit, always use the manufacturer's total product dimensions rather than the screen diagonal.
The recommended viewing distance for a 109 cm (43-inch) TV is between 1.6 m and 2.7 m. This is based on 1.5× to 2.5× the screen diagonal. At 1.6 m, 4K content looks sharp with no visible pixels. For standard HD content, sitting around 2.0–2.2 m is comfortable. The 43-inch size is especially popular for bedrooms and kitchens where viewing distances tend to be shorter. For rooms where the sofa is consistently more than 3 m from the screen, a 50 or 55-inch TV will serve you better.
Yes, 109 cm and 43 inches are effectively the same TV size. A 43-inch screen has an exact diagonal of 109.22 cm (43 × 2.54), which rounds to 109 cm. The 2 mm difference is negligible in practice. If you see a listing for a "109 cm TV" in a European shop and a "43 inch TV" in an international one, they refer to the same screen — the discrepancy is purely a matter of unit rounding between metric and imperial measurement systems.
