The phrase "a size of less" is not correct in standard written English.
It may be intended to express a measurement or quantity that is smaller than a specified size, but the phrasing is awkward and unclear.
Example: "We need to order a size of less than medium for the new uniforms."
Alternatives: "a smaller size" or "a size smaller than".
The total area of occupation has a size of less than 7000 km2.
90% of the InDels had a size of less than 10 bp.
Transmission electron microscope observations show that the produced particles had a bcc structure with a size of less than 50 nm.
Atomic force microscopy and confocal fluorescence microscopy demonstrate that approximately 30% of diamond nanocrystals with a size of less than 10 nm are fluorescent and have a remarkably long spin decoherence time (2.7 μs for a 7 nm diamond nanocrystal).
Whereas the TRIP occurred in coarse γ-austenite grains at small tensile strains, the TWIP took place in fine γ-austenite grains with a size of less than ∼10 μm at large tensile strains.
Long baseline slopes are assessed based on LOLA, while craters and boulders are detected both visually and using computer tools in Lunar Reconnaissance Orbiter Camera (LROC) images, down to a size of less than 2 m, and size-frequency distributions are generated.
Optimum process conditions in terms of both char yield and zinc adsorption performance were achieved from slow-pyrolysis at 300 °C for 2 h using a feedstock with a particle size of less than 1 mm.
A grid size of less than a few km was needed to capture the structure of the convective scale background error covariance.
The test for MSWI BA was carried out on a sample crushed to a particle size of less than 4 mm.
NICAM is known as the first practically used global non-hydrostatic atmospheric model and was recently run with a mesh size of less than a kilometer over the global spherical domain.
The overall outcome was that already for a particle size of less than 1.5 mm a sufficient analytical result can be obtained.
