GBPUSD Lot Size Calculator
On a $10,000.00 account, risking 2% ($200.00) with a stop of 20 pips, GBPUSD sizes to 1.00 lots. One pip on 1.00 lot is $10.00. The loss at that rounded size is $200.00, with no spread and no commission.
GBPUSD uses the same 100,000 unit contract and the same $10.00 per pip as EURUSD, because the quote currency is USD. Cable's price is higher and stops are often wider, so this grid uses 15, 30 and 60 pips. An EURUSD lot copied onto GBPUSD is the right size only when the stop, the spread and the risk match.
GBPUSD contract: 100,000 units per 1.00 lot. 1 pip = 0.0001. A 0.01 lot is $0.10 per pip, a 0.10 lot is $1.00, and 1.00 lot is $10.00. The quote currency is USD, so the 2026-10-15 bundled rates are not applied. Minimum lot 0.01, step 0.01. The lot rounds down, so the loss at the stop stays at or under the risk when spread and commission are left at zero.
The risk table for GBPUSD uses stops of 15, 30, 60 pips. On $10,000.00 at 2% those three stops size 1.33 lots, $199.50 at the stop; 0.66 lots, $198.00 at the stop; 0.33 lots, $198.00 at the stop.
