Good rule of thumb (and most code books) state that the maximum overhang should be no more than one-third the total length of the joist. This provides two-thirds of the joist as support.
The answer requires more information. Joist depth Joist spacing Wood Species Engineered wood will be based on the manufacturers information. Hope this helps! TL North, CBO
It depends on the sise and grade of the joists.
It depends on the joist thickess, spacing and load it is carrying. There is not a answer without more information.
Deck joists can lift out of their hangers at the rim/band if too many people are at the cantilievered section of a deck. Therefore deck joists that cantilever out past the deck posts, should never overhang the girder they rests on by more than how far?
A cantilever deck is a deck that is suspended by joists that stick out of the structure. The distance the deck sticks out of the structure is one-third the total length of the cantilever beams that enter the structure. Usually these beams are bolted to (or sistered) to the second story floor joists or the roof trusses. Onto these beams are attached the floorboards that make the surface of the deck. And onto those the railings are attached. Hope that helps :-)
Not knowing if the joist are in need of repair from rot (deterioration) or broken/damaged then replace ment of joist may be necessary. First get a replacement joist of the same or better species and treatment content and dimensions as the existing joist. Then cut the joist to the same length. You may have to cut a small angle on the bottom end of the joist to aid in working it over and between the girts and decking boards. Work the joist within a few inches of the joist to be replaced. Use a short 4x4 to drive the joist or a wood block to strike with a hammer. Take a couple of scrap 2x's and temporarily fasten to the girts and new joist to prevent movement. Then you may try a couple methods to remove the old joist. If the decking is fastened with screws then simply backout the screws. If it is nailed, then a 10 lbs. hammer can often remove most anything you need and is a great stress reliever but I recomend you use a reciprocating saw to cut the fasteners between the joist and decking. Usually the vibration of the saw and nails being cut will loosen the deck side of the fasteners and allow you to go top side and pull the old nail halves out. Once the old joist and fasteners are out you can carefully work the new joist in place. I recommend fastening the old decking to the new joist with properly coated screws or a hotdipped galvanized rink shank nail. Repeat joist replacement as necessary on other joist.
.I beleive 24" is universal standard
Deck building calculators to help calculate concrete, joist and beam span, stair stringer layout, baluster, deck boards and deck load too. hi there here it is

The bigger, the stronger generally, and the more weight they can support. But the footers and support beams have to be sized properly also.
there is no limit
