Office Space Requirement Calculator

Size your office before you sign. Enter headcount, sector, grade and city; we return a recommended leasable area with a low–high band and an annual rent envelope at current Riyadh and Jeddah benchmarks. Take the result into the Occupancy Cost calculator for fully-loaded SAR/employee/year.

Organisation

Tell us how many people you are sizing for and the sector. Sector sets the density band.

Headcount Sector

Building

Grade and city set the rent benchmark used for the annual envelope.

Grade City

Riyadh Grade A, SAR 2,750/sqm/yr (Knight Frank Q3 2025 cited average for Grade A office stock, +15.1% YoY, 98% occupancy).

Layout

Workspace mix and circulation factor convert usable space into leasable area.

Workspace mix Circulation factor

Multiplies usable sqm to give leasable/NIA. Saudi office floorplates typically run 1.30–1.40 depending on core efficiency.

Saudi rules & benchmarks

Q1 2026 rent benchmarks Rent benchmarks aligned with Knight Frank Saudi Arabia Q3 2025 Commercial Market Overview (Grade A) and the SAT Riyadh Commercial Rent Index Q1 2026. JLL Q1 2026 KSA Office Market Dynamics and CBRE Q4 2025 Saudi Real Estate Market Review confirm directional momentum.
Prime stock premium Prime/trophy stock in KAFD and Diriyah Gate runs 30–40% above benchmark per JLL, see the SAT Rent Index for district-level granularity.
Riyadh + Jeddah density bands Density bands reflect observed Riyadh and Jeddah Grade A occupier delivery.
1.35 circulation factor Circulation factor default 1.35 reflects typical Saudi office floorplate efficiency (NIA/GIA ratio).
Grade A vs Grade B Grade B reduces each band by ~2 sqm because B-stock tends to be older floorplates with less efficient cores.
