1/2, 5/8, 3/4 depending on what it needs to do.
Plywood's most common use is in exterior sheathing and in flooring substrate. Plywood is also commonly used for concrete form work. Plywood is layered and the layers are oriented at right angles to provide strength and dimensional stability. Plywood also comes in a few thicknesses depending on the application.
The most common varieties of softwood plywood come in three, five or seven plies with a metric dimension of 1.2 m × 2.4 m or the slightly larger imperial dimension of 4 feet × 8 feet. Plies vary in thickness from 1/10" through 1/6" depending on the panel thickness. Roofing can use the thinner 5/8-inch plywood. Subfloors are at least 3/4-inch depending on the distance between floor joists. Plywood for flooring applications is often tongue and grooved. The mating edge will have a "groove" notched into it to fit with the adjacent "tongue" that protrudes from the next board. This keeps the boards from slipping past each other providing a solid feeling floor when the joints do not lie over joists. Tongue & groove flooring plywood is typically 1" in thickness.

Plywood is a wood product that is produced by gluing some plies of hardwood or softwood together. It is resistant to many common annoyances found in solid wood, such as shrinking, cracking and twisting. Plywood is also a strong and durable material and it is more environmentally conserving, due to the fact that plywood can be made into sheets that are much wider than the original trees. Different types of plywood are used for a wide variety of different things, including dog kennels, flooring, furniture, fences, framing, barns, yachts, roofs, mailboxes and shelving.
The type of wood used in hardwood flooring varies. The most common type of wood used in hardwood flooring is timber. Another common but more exotic wood in hardwood flooring is bamboo.

Valley flashing typically does not come in standard sizes, as it is often custom-fabricated to fit the specific dimensions and angles of a roof's valley. However, manufacturers may offer common size options that can accommodate typical roofing configurations. It's important to measure the valley accurately and consult with suppliers to ensure the correct fit for your roofing project.
Plywood became a common material used in home construction during the mid-20th century, gaining popularity for its strength, versatility, and cost-effectiveness.
A common fake hardwood floor name used to describe laminate flooring is "faux wood."
The type of flooring for lofts tends to be that made of wood, or laminate flooring. Concrete or that made of stone is avoided as it is too heavy for most buildings.
Oak is generally thought of as a durable flooring. It is the most common wood floor in North America. The Janka Hardness Scale puts white oak at 1360 and red oak at 1290. In comparison, hard maple is a little higher at 1450 and southern yellow pine at 870. The construction of the floor will have a great deal to do with how this floor will wear. The under part of the floor ideally should be made of plywood and not HDF or MDF. Assuming this, oak engineered flooring is a durable choice for most homes.
The best options for installing wood flooring in a basement are engineered wood flooring or luxury vinyl plank flooring. These options are more resistant to moisture and humidity, which are common in basements, compared to solid hardwood flooring. It is important to ensure proper moisture barriers and ventilation to prevent damage to the wood flooring.
