Size Charts – All the Information for Your Projects

A wood-weight chart is a planning reference, not a promise about an individual board. The same species can weigh differently as moisture changes, and density varies among trees and pieces. Check the condition and units before estimating a lift, shipment, or storage load. Measurement reference; schematic, not to scale. Green [...]

Thermal conductivity, conductance, and R-value all describe heat transfer, but they answer different questions. Conductivity describes a material property per unit thickness; conductance describes a specimen at a stated thickness; R-value describes resistance for the layer being compared. Read the property name, units, thickness, and test conditions together. Measurement reference; [...]

Machinability is not one universal score. A species may plane cleanly yet perform differently in turning, boring, or sanding. Results also depend on grain, moisture, defects, tool condition, feed, and the job's quality target. Measurement reference; schematic, not to scale. Selected historical test resultsThis table summarizes four operations for six [...]

Wood strength depends on species, grain direction, moisture, defects, and how a member is graded and loaded. A species comparison helps explain material behavior, but clear-wood test results are not a load chart for a board or beam. Measurement reference; schematic, not to scale. Read the property names firstThe table [...]

Mikuni Pilot Jet Drill-Size Reference: Diameter Equivalents and Cautions Important: do not drill genuine Mikuni jets. Jet-number markings are not universal or interchangeable with orifice diameter, drill size, or flow rate. Buy the correct genuine jet for the carburetor and use the manufacturer's tuning information. Diameter Equivalents and Nearest Drill [...]

Scooter CVT Drive Belt Size and Fitment Guide Quick answer: do not choose a scooter CVT belt by engine size alone. Copy the complete marking, then confirm its dimensions and fitment for the exact make, model, year, engine and transmission in a manufacturer or parts-catalog listing. How to Check a [...]

Metric Socket Head Cap Screw Size Chart Quick answer: the hex key is selected by the screw's internal socket size, not by its thread diameter. For example, an ISO 4762 M6 socket head cap screw uses a 5 mm hex key; M8 uses 6 mm and M10 uses 8 mm. [...]

Screwdriver Sizes: Phillips, Slotted, Torx and More Quick answer: match the driver profile and size to the fastener recess. A Phillips tip is not the same as Pozidriv, and internal Torx (T) sizes are not external Torx (E) socket sizes. The tip should seat fully with little side play. Common [...]

Compressed Air Pipe Sizing: What the Chart Can Tell You Quick answer: there is no reliable one-size-fits-all CFM-to-pipe-size chart without design assumptions. Flow demand, operating pressure, pipe length, fittings, pipe bore and the allowable pressure drop all affect the result. Information Needed to Size Compressed-Air Piping The former CFM ranges [...]

EMT Conduit Sizes: Dimensions and Outside Diameter Quick answer: trade size is a label, not a measured diameter. For example, 1/2-inch EMT has a nominal outside diameter of 0.706 inch. Check the conduit type and product markings when selecting connectors or checking clearances. EMT Outside Diameter and Internal Area The [...]

Parker O-Ring Size Chart: Series 2 and AS568 Dash Numbers Quick answer: Parker Series 2 numbers cross-reference to AS568 dash sizes. Use the table to compare nominal ID, OD, and cross-section with Parker-listed actual dimensions and tolerances; confirm the compound and seal design separately. Parker Series 2 O-Ring Sizes The [...]

Propane Gas Pipe Sizing: Safety and Planning Guide Safety note: there is no one-size-fits-all propane pipe chart. Pipe capacity depends on the locally adopted code, pipe material, gas pressure, regulator setup, appliance demand, pressure drop, and equivalent length. A qualified gas fitter must determine the design and verify it against [...]

Cannondale Mountain Bike Size Chart: Rider Height and Frame Size Quick answer: Cannondale does not recommend choosing a frame by rider height alone. Measure rider standover, then compare it with the geometry chart for the exact bike model and year. How to Choose a Cannondale Mountain Bike Size XS, S, [...]

Ideal Hose Clamp Size Chart: Hy-Gear 63-4 Series Quick answer: measure the outside diameter of the hose after it is installed on the fitting, then choose a clamp whose listed working range includes that measurement. This chart covers the Ideal Tridon Hy-Gear 63-4 series only. Hy-Gear 63-4 Clamp Size Chart [...]

Peerless Tire Chains Size Chart: Fitment Lookup and Safety Notes Quick answer: read the complete tire size from the sidewall, check your vehicle manual for chain restrictions, then search that tire size in Peerless' current finder. Confirm the exact product match and test-fit the chains before travel. How to Check [...]

2012 Jeep Liberty Tire Size Chart Quick answer: Jeep's 2012 Liberty specifications list P225/75R16 for Sport, P235/70R16 as an available Sport all-terrain option, P235/65R17 for Limited, and P245/50R20 for Jet. Match the exact tire size and ratings on your vehicle's driver-side door or B-pillar placard. Factory-Listed Tire Sizes These are [...]

PEX Tubing Size Chart Quick answer: North American plumbing PEX is commonly sized as CTS tubing. The nominal label is not its measured inside diameter: 1/2-inch PEX has a 0.625-inch average outside diameter and about a 0.475-inch calculated inside diameter in the PPI reference. Standard CTS PEX Dimensions This chart [...]

2019 Jeep Grand Cherokee Tire Size Chart Quick answer: the 2019 Grand Cherokee used several factory tire sizes depending on trim and package: P245/70R17, 265/60R18, 265/50R20, and P295/45ZR20. Match your specific Jeep to the tire and loading information placard on the driver-side door or B-pillar before buying. 2019 Factory Tire [...]

Bike Inner Tube Sizes Chart Quick answer: match the tire tube to the exact ETRTO diameter printed on your tire, then choose a tube range that includes the tire width. For example, a 37-622 tire needs a 622 mm tube sized for 37 mm width. Do not choose by “26 [...]

2019 Silverado Tire Size Chart Quick answer: 2019 Silverado tire sizes vary by model series and factory package. The new-body Silverado 1500, carryover 1500 LD, 2500HD, and 3500HD use different size ranges.

Test-fit the chains before traveling. Check Fitment Before Choosing [...]

Allen Wrench Size Chart Quick answer: measure a hex key across its flat sides and use the matching inch or metric size. The conversion columns are mathematical equivalents, not substitute tool sizes; a close-fitting wrong key can damage the fastener. SAE Allen Key Sizes This selected inch-size reference includes common [...]

Garage Door Torsion Spring Wire Size and Color Chart Safety warning: this chart is for identifying DASMA torsion-spring wire colors only. DASMA says its chart is not for homeowners or maintenance personnel to replace garage-door springs. Spring replacement should be performed only by a trained door-systems technician.
