Measuring your balcony correctly is the single most important step before buying urban outdoor furniture. A few wrong numbers can mean a table that blocks your door or chairs that leave no walking space. Here’s the best method, tailored for small city balconies.
1. Measure length and width at multiple points
Start by measuring the full length and width of your balcony floor. Because many urban balconies are not perfectly rectangular, take measurements at three spots along each side (near the building, in the middle, and near the railing). Use a metal tape measure for accuracy. Record the smallest measurement in each direction—furniture that fits the narrowest point will fit everywhere.
2. Note the exact usable floor area
Subtract space taken by permanent fixtures: door swings, radiators, air conditioner units, or built-in planters. Also account for the space needed to open your balcony door fully. A common mistake is buying furniture that overlaps the door’s path. Mark these “no-furniture zones” on your drawing.
3. Measure the height and depth of doorways
If your balcony access has a step or a narrow doorframe, measure the height and width of the opening. Your furniture parts (especially larger items like a sofa or table) must pass through. Write down these clearance dimensions to avoid returns.
4. Check floor slope and drainage
Most balconies slope slightly (about 1–2%) away from the building for water runoff. Use a level to find the direction and degree of slope. Furniture legs may need adjusters or shims to sit flat. This is critical for dining tables or chairs with straight legs.
5. Photograph and sketch the layout
Take photos from every corner, and draw a simple floor plan on graph paper (scale 1 square = 10 cm). Include windows, doors, railings, and any columns. Then cut out paper templates of potential furniture pieces at the same scale. Move them around to test walkways and seating arrangements—this visual test is the best way to confirm fit.
6. Leave generous clearance
For any furniture, leave at least 60 cm (24 inches) of walking room on main pathways and 30 cm (12 inches) around seating areas. On a small balcony, even 10 extra centimeters can make the difference between a relaxing space and a cramped one.
7. Double-check vertical space
If you’re adding a hanging chair, tall planters, or a foldable table, measure the clear height from floor to overhead beams, awning, or the balcony above. Also note the railing height—some cities have code requirements for furniture below railing tops.
By following these steps, you will have a complete dimensional profile of your balcony. Use it to filter furniture listings by exact measurements, not just “small size” labels. When in doubt, choose pieces that are slightly modular or foldable—urban outdoor furniture designed for tight spaces often includes clever stacking or nesting features. Your careful measurement is the foundation of a balcony that feels spacious, functional, and truly yours.
