The chain link post calculator splits a run into the two post classes a chain link framework actually needs: heavier terminal posts at every corner, end and gate opening that absorb the tension of stretched fabric, and lighter line posts in between that mainly support the top rail. This is a narrower breakdown than the full chain link fence calculator gives, which is useful when you already know your total length and height and just need an accurate post and fitting count, including loop caps for line posts and dome caps, tension bands and brace bands for terminal posts.

Line post spacing tops out around 10 feet for standard residential chain link, and that interval should come down toward 8 feet in high wind areas or wherever privacy slats will be woven into the fabric later, since slats turn open fabric into something closer to a solid panel that catches real wind load. Terminal posts need deeper embedment than line posts, commonly 30 to 36 inches against 24 to 30 for line posts, because they carry tension in addition to the vertical panel weight. The fence post depth and setting guide covers that depth difference for posts generally, and the chain link fence installation guide covers the full stretch and lace sequence once posts and fabric are both on site.

Terminal post holes take noticeably more concrete than line post holes because they are both wider and deeper, and the concrete bags calculator converts whatever hole dimensions you use into an actual bag count for 50, 60 or 80 pound mix rather than leaving you to guess at a yard total. Posts and fabric are sized separately on this site, so once the post count here is settled, the chain link fabric calculator works out how many rolls, splices and a cut piece the same run needs, and the general fence post calculator is a useful comparison if you want to see how the chain link post split stacks up against a simpler single post class fence.

Every walk gate adds two terminal gate posts that are not part of the line post run, and a double swing driveway gate adds two more, heavier still, on either side of the opening; the gate post calculator sizes those separately from the perimeter count here. Terminal posts cost more per unit than line posts, so an accurate split between the two categories matters for a realistic budget, which the chain link cost per foot guide and the wood vs chain link fence cost comparison both put in context against other common materials. The metal fence calculators hub links back to the full chain link fence calculator and to aluminum and ornamental options for anyone still deciding on a material before finalizing a post plan.

Line posts can sometimes be driven directly into dense, stable soil with a pneumatic post driver rather than set in concrete, commonly 3 to 4 feet deep, which can speed up a long run of line posts considerably compared with digging and pouring each one. Terminal posts are a different story: because they carry real tension once the fabric is stretched and the brace and tension bands are tightened, a driven terminal post without concrete is far more likely to lean or walk over time than a line post in the same soil, so corner, end and gate posts should go in a proper footing even on a job where line posts are driven. Soil type matters for this decision more than personal preference does, since a driven post approach that works fine in dense clay can fail in sandy or loose fill soil where the pipe simply does not grip well enough to stay plumb under load.

Fitting counts scale with post class rather than with total run length alone, which is part of why this calculator separates terminal from line posts instead of giving one combined number. Every corner post takes two full sets of brace bands and tension bands, since it resists pull from two directions, while a straight end post only needs one set, and overlooking that doubling at corners is a common way to come up short on hardware even when the post count itself was right. Keeping the terminal and line post fitting lists separate through ordering, rather than averaging them into one hardware count per post, is the more reliable way to make sure every corner actually gets the extra bands it needs before installation day.

Loop caps on line posts do more than cap the open pipe end against rainwater; they also let the top rail slide freely through each post as it is threaded along the run, so the cap size has to match both the line post diameter and the rail diameter rather than just the post alone. Dome caps on terminal posts serve a purely weatherproofing role since no rail passes through a terminal post the way it does through a line post, which is why terminal and line post caps are different parts even though both sit on the same nominal pipe sizes. Getting post diameters right matters for cap selection too: residential line posts commonly run about 1 and 7/8 inches outside diameter while terminal posts step up to roughly 2 and 3/8 inches, and mismatching a cap to the wrong post class is a small but avoidable mistake once the terminal and line post counts from this calculator are in hand.
