The phrase "a relatively large size" is correct and usable in written English.
It can be used when comparing the size of an object or entity to others, indicating that it is larger than average but not excessively so.
Example: "The new storage facility has a relatively large size compared to the previous one, allowing for more inventory."
Alternatives: "a fairly large size" or "a moderately large size."
Plateosaurus was among the earliest dinosaurs to attain a relatively large size, growing to about 8 metres (26 feet) long.
In all live-bearers the young are born at a relatively large size and are few in number.
The new species reaches a relatively large size, which may exceed 20 cm, and is characterised by a very unusual hinge line morphology, straight without a bulge of the resilium.
Underlying the program is a method to convert fatigue lives tested at different cyclic stress levels into the equivalent lives at an arbitrary stress level, by which a relatively large size sample is established.
Copper is incorporated as metal particles with a relatively large size distribution ranging from 20 to 400 nm (with a large majority in 20 100 nm) depending on the copper content of the films.
Graphitic carbon-based electrocatalysts with a relatively large size, rich microporous structure and high surface area could possess better structural stability and enhanced conductivity than those of small-sized carbon nanostructures (e.g., nanodots).
This would in turn prevent the benzene molecules, with a relatively larger size compared to water molecules, from diffusing by a fluid-like streaming mechanism that is required by the model.
Compared to those tiny particles, the rod-like products have a relatively larger size and smaller ratio surface, leading to less surface defects.
Although this alternative formulation has a relatively larger size, it eliminates the nonlinear structure in bipolar max-(T_{L}) equations and allows us to tackle the associated optimization problem by the usual optimization techniques.
This was probably because they used a relatively larger size of battery than conventional hearing aids.
ODN-MS has a highly negative surface charge (−37.14 ± 1.46 mV) due to the presence of DNA and a relatively larger size (∼1800 nm).
