What size stand does a 40-inch TV need?
Check the exact model and stand configuration. The support footprint tells you the width and depth occupied by the support; stand separation alone does not establish that footprint. Also check the furniture's load capacity and the manufacturer's installation instructions.How to measure a TV stand.
Will a 40-inch TV fit in my space?
Measure the available opening and compare it with the cabinet or assembled dimensions above. Allow for the ventilation, cables and access required by the exact model's instructions. Screen geometry alone cannot answer this.Measure an alcove before choosing.
Compare another screen size
Compare the screen rectangle before checking an exact model's cabinet and stand. These calculated 16:9 dimensions exclude bezels and stands; a size class alone does not establish whether a TV fits your space.
